  • Study of the Subthreshold Performance and the Effect of Channel Engineering on Deep Submicron Single‐Stage CMOS Amplifiers

    This chapter outlines the advantage of using a single‐stage complementary metal oxide semiconductor (CMOS) cascode amplifier over CMOS current‐source amplifier in the subthreshold regime of operation. Apart from extremely low power dissipation, the cascode amplifier is able to produce high voltage gain and low output capacitance. The impact of using a single‐halo (SH) or lateral‐asymmetric channel (LAC) doping on 180 nm MOS devices of the amplifier circuit is investigated. The CMOS PTAT (proportional to absolute temperature) circuit as a temperature sensor for low‐power applications is also studied.

  • ActiGait®: A Partly Implantable Drop-Foot Stimulator System

    ActiGait is a four-channel partly implantable neuroprosthesis to control ankle dorsiflexion during the swing phase of gait. It was the goal of the developers to make a device that was easily handled by users with various levels of disabilities. To ensure optimal application of the ActiGait during market introduction, additional monitoring tools were applied and developed such as preoperative and postoperative magnetic resonance imaging (MRI), intraoperative fluoroscopy, and surface recordings of artifacts generated by the electrical stimulation of the nerve. By employing close monitoring during the establishment of new ActiGait clinical centers, ActiGait has been shown to be well accepted by users in several European countries. Experiences with the ActiGait have shown that thorough and targeted knowledge transfer to new clinical ActiGait centers, application of suitable monitoring tools, and close monitoring are all decisive in bringing a medical device such as an implantable drop-foot stimulator system successfully on the market.

  • Impact of Halo Doping on the Subthreshold Performance of Deep‐Submicrometer CMOS Devices and Circuits for Ultralow Power Analog/Mixed‐Signal Applications

    In this chapter, the effects of halo doping – both double‐halo (DH) and single‐halo (SH) or lateral asymmetric channel (LAC) doping – on the subthreshold analog performance of 100 nm CMOS devices are investigated systematically with extensive process and device simulations. In the subthreshold region, although halo doping is found to improve device performance parameters (such as the transconductance generation factor_g__m_/_I__D_, output resistance_R__o_, and intrinsic gain_g__m__R__o_) for analog applications in general, the improvement is significant for the LAC devices. A low angle of tilt of the halo implant is found to give the best improvement in both the LAC and the DH devices. The results show that CMOS amplifiers made with halo implanted devices have higher voltage gain than their conventional counterparts, and a more than 100% improvement in the voltage gain is observed when LAC doping is made on both the p‐ and the n‐channel devices of the amplifier.

  • Implantable Health Care System Paradigm

    This chapter describes the implanted antennas to be applied to medical situations. One is the PIFA loaded onto a cardiac pacemaker for use in the 400MHz Medical Implant Communications Service (MICS) band; another one is the helical dipole antenna for the industrial scientific medical (ISM) band. It evaluates the implanted antenna models were numerically analyzed by the finite-difference time-domain (FDTD) method and the antenna characteristics. The chapter analyzes the antenna characteristics of an antenna implanted in a multilayer medium model. Moreover, implanted antennas were buried into high- resolution numerical human models and the effectiveness of these antennas and the validity of the multilayered structure model were investigated by numerical analysis. As a result, it is possible to use these implantable antennas for health care wireless communication systems.

  • Novel Antenna Designs and Characterization Methodologies for Medical Diagnostics and Sensing

It provides a brief summary of the various methodologies for the design and development of these antennas using numerical simulations and characterizations. The chapter discusses the antenna performance parameters in the human body environment, a thorough comparison was conducted between the proposed design and some other existing antenna topologies in terms of link budget estimation, and proposes a wireless power transfer enabled frequency reconfigurable system and provides initial inductive link budget calculations. Next, it proposes a medical monitoring and sensing system with the capsule antenna system using RFID technology. Lastly, the chapter discusses an RFID bio-tag which can be used for patient monitoring, including vitals and location, in hospital environments.

  • Power/Data Telemetry Techniques for Implants or Wearable Systems

    The need for energy efficient and multi-functional implanted or wearable devices has driven research into novel power and data telemetry techniques. For both implantable and wearable devices, specifications of the power and data telemetry need to be identified based on the underlying applications. However, few general methods and technologies have been developed to ease the constraints of these systems. For example, multiple wireless power transfer (WPT) methods. This chapter presents two design examples that discuss the implementation of a leading implanted retinal prosthesis and a wearable electronics based on body-area network (BAN). For WPT systems, the efficiency of the power transfer depends on the operating frequency, operating distance, and the dimensions of the external and implant coils. The chapter describes three methods based on the operating frequency and electromagnetic field source: inductive coupling, high frequency power transfer, and permanent magnet-based power transfer.

  • Design Considerations of Biomedical Telemetry Devices

    The specifications for an implantable medical device (IMD) are provided by the application but share a common set of constraints in size, power, and functionality. This chapter provides a brief overview of the design of biomedical telemetry devices and in particular IMDs using inductive links. The basic system architecture and inductive link fundamentals are discussed, as well as methods and circuits for power transfer and data communication. Safety issues relating to overheating of body tissue as a result of increase of temperature are also examined. There are several methods of harvesting energy for IMDs such as kinetic, thermoelectric, fuel cells, infrared radiation, low- frequency magnetic fields, and inductive links. Data communication is called the downlink from the transmitter to the implant, and the uplink from the implant to the transmitter. Due to dual data and power transfer, the carrier amplitude is greater than or equal to the supply voltages.

  • Impact of a Spacer‐Drain Overlap on the Characteristics of a Silicon Tunnel Field‐Effect Transistor Based on Vertical Tunneling

    A tunnel field‐effect transistor (TFET) in which the dominant carrier tunneling occurs in a direction that is in line with the gate electric field, shows great promise for sub‐0.6 V operation. A detailed investigation, with the help of extensive device simulations, of the effects of a spacer‐drain overlap on the device characteristics of such silicon TFETs is reported in this chapter. It is demonstrated that a supersteep subthreshold swing and a significantly reduced OFF‐state current_IOFF_can be achieved by appropriate designing of the spacer‐drain overlap. An investigation of the influence of the drain potential on the device characteristics reveals that the absence of a tunnel‐resistance limited region results in long‐channel metal oxide semiconductor FET‐like output characteristics for such a structure. Short‐channel effects, such as drain‐induced barrier lowering, are also greatly suppressed in it. Results of an investigation of the scaling properties of such devices are also reported.

  • Stimulator Paradigm: Artificial Retina

    Implanted telemetry devices used for medical implants are affected by their surrounding environment since tissues are frequency-dependent lossy dielectric materials. This chapter focuses on the considerations and methodologies for the design of high-performance and small-size antennas appropriate for intraocular implants. The multicoil approach for inductive coupled telemetry offers high power transfer efficiency for biomedical telemetry. Having multiple control parameters to tune efficiency, voltage gain, and bandwidth, multicoil telemetry systems are in general more flexible than dual-coil systems. The artificial retina is undergoing clinical medical trials in several countries, and it can be available to patients worldwide. The implementation of flexible small antennas using liquid metals holds the promise of better fitting implantable conformal devices, which is important in the proximity of delicate biological structures such as the eye's retina and smaller incisions for implant surgery.

  • Device Processing of Silicon Carbide

    Many processing steps are required to fabricate complex electronic devices, including doping by ion implantation, patterning, etching, oxidation, passivation, and metallization. The process flow in SiC device fabrication is similar to that in silicon technology but several unique processes, with particular requirements, are also needed because of the unique physical and chemical properties of SiC. This chapter introduces the fundamental aspects and technological development of ion implantation, etching, oxidation, interface passivation, and Schottky and ohmic contacts in SiC.
