Filter-shape dependence on attenuation mechanism in channelized dynamic spectral equalizers

The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2002

Summary form only given. Today's optical networks require optical add-drop capability as well as broadcast-and-select topologies. Such capabilities are enabled with high-resolution, channelized dynamic spectral equalizers (DSE), which can attenuate each optical channel independently to an extinction exceeding 30 dB in a DWDM system. Several implementations of channelized DSE are based on a dispersive, free-space imaging configuration, projecting the light ...

  • On the Approximation Problem in Network Synthesis

    A procedure is presented for the synthesis of a network to yield a prescribed magnitude versus frequency characteristic. The given characteristic is replaced by a sequence of straight line segments of arbitrary slope. Each line segment is associated with a zero-pole pair properly placed on the real p axis, where p is the complex frequency variable. In this manner a real, rational network function is obtained whose magnitude variation approximates the given one. Methods for predicting the realizability of the approximating function are discussed in the application to the design of two terminal and two-terminal pair networks. To illustrate the methods outlined in the paper, a complete procedure is given for the design of attenuation equalizers using constant-resistance ladder sections.

  • Filter-shape dependence on attenuation mechanism in channelized dynamic spectral equalizers

    Summary form only given. Today's optical networks require optical add-drop capability as well as broadcast-and-select topologies. Such capabilities are enabled with high-resolution, channelized dynamic spectral equalizers (DSE), which can attenuate each optical channel independently to an extinction exceeding 30 dB in a DWDM system. Several implementations of channelized DSE are based on a dispersive, free-space imaging configuration, projecting the light emerging from the input fiber via imaging lenses and a diffraction grating onto a pixelated device plane. The active pixelated device can be chosen from multiple technologies, however liquid crystal (LC) based modulators and micro-electro-mechanical system (MEMS) tilting micro-mirrors are the favored technologies.

  • A Reconfigurable Microwave Equalizer With Different Maximum Attenuations Based on RF MEMS Switches

    The design, fabrication, and measurements of a novel reconfigurable microwave equalizer based on RF micro-electro-mechanical system (MEMS) switches for adjusting the maximum attenuations of microwave signals are presented in this letter. The reconfigurable equalizer is driven by four lateral dc-contact RF MEMS switches, which can select the different attenuation resistances and obtain various maximum attenuations compared with the traditional microwave equalizer with fixed maximum attenuation. The proposed reconfigurable equalizer is fabricated by MetalMUMPs process. The experimental results show that the reconfigurable equalizer can realize four maximum attenuations of 7, 6.6, 5.9, and 5.6 dB by the actuation of RF MEMS switches, the reflection losses are all below -16 dB at the frequency range from 17 to 19 GHz, the experimental results agree well with the theory.

  • A 2.5-Gb/s 0.13-μm CMOS current mode logic transceiver with pre-emphasis and equalization

    A 2.5-Gb/s current-mode logic (CML) transceiver is implemented in 0.13 - mum CMOS technology for serial inter-chip interconnection. To compensate the channel attenuation and other impairments, pre-emphasis circuit is included at the transmitter and equalizer at the receiver. 6-GHz 3 dB bandwidth is achieved through the use of active inductors instead of online spiral inductors. DC offset compensate circuits are employed in the output and input buffers to keep the common mode voltage stable. Layout simulation demonstrates the effectiveness of the transceiver. This transceiver consumes only 160 mw of power with 2.5v power supply. The die area of transmitter and receiver are 0.015 mm2, 0.01 mm2respectively. The transceiver can be operated at 2.5-Gb/s with 100 mv receiver sensitivity.

  • Increase optical node output power using predistortion

    A predistortion technique capable of improving CTB by 10 dB has been demonstrated. The output power of the broadband RF amplifier can deliver as much as 51 dBmV with 7 dB slope under 78 NTSC channel loading while CTB performance of 64 dB was obtained with the help of a predistortion technique.

  • VLSI implementation of multiplier-free low power baseband filter for CDMA systems

    A multiplier-free baseband filter is proposed for the low power VLSI implementation in a code division multiple access (CDMA) system. The new computational efficient filter structure is based on a novel prefilter structure involving a pair of even and odd length FIR filters with the same band edges. It is shown by example that the new structure not only achieves 45.8% savings in the number of multipliers, but also reduces the word length requirement for the coefficients of an IS-95 CDMA baseband filter. The VLSI implementation shows that the new structure reduces both the chip area and power consumption considerably compared with the direct-form implementation.

  • Delay line adjustment for the optimization of digital continuous time filters

    Systems which perform digital signal processing in continuous-time are attractive for a number of applications like biomedical implants, hearing aids, remote sensors, telecommunications, and audio and speech processing. While the inherent advantages of digital implementations with respect to programmability and noise immunity are retained by this kind of signal processing, they have some interesting advantages compared to classical sampled data systems. A main difference to sampled data systems is the realization of the delay elements which are implemented as quasi-continuous time delay lines. In this paper, it will be shown that an additional degree of freedom for adjusting the delay lines, and therefore optimizing the filter characteristic can be achieved for filter structures, well-suited for continuous time realization.

  • Comparison of DFT and cosine modulated filter banks in multicarrier modulation

    This paper examines the comparative performance of DFT and cosine modulated filter banks used in multicarrier signaling over a linearly distorted channel, affected by both white Gaussian and NEXT noise. The interference caused by the overlap in the frequency responses of the signaling filters is calculated analytically and simulation results are given to support the theoretical calculations. It is shown that without any pre-receiver processing, the level of interchannel interference is lower in the cosine-modulated family of filters, because of their higher stopband attenuation. We also examine how pre-receiver processing (short equalizer plus cyclic prefix) can lower the level of interference, especially in the DFT system. Finally the capacity of a sample channel, similar to the twisted-pair channel of a subscriber loop, is calculated with and without the effect of interference taken into consideration.

  • Application of Electrical Networks to Sound Recording and Reproducing

    The use of electrical networks with recording and reproducing systems to accomplish beneficial results has been steadily increasing. Two types of networks are in general use, namely, wave-filters and attenuation equalizers. This paper discusses in some detail the use of these networks with sound systems as reflected by present practices and later presents practical data for engineering the networks with a minimum of time and effort. The uses to which attenuation equalizers are put divide these networks into two general classes: first, fixed equalizers to provide fixed equalization for sound channels; and, second, variable equalizers to provide means for varying at will the relative amplitudes of the frequency components of sound signals. Although the means for engineering variable networks is far from being ideal, the review given in the paper of present practices should be valuable.
