  • GaAs bipolar wideband oscillators

    The aim of this work was an investigation of the GaAs heterojunction bipolar transistor (HBT) for wide tuning range, low phase noise oscillators including, for the first time, a YIG-tuned HBT oscillator. The article describes two types of electronically tuned oscillators, firstly ones based on varactor tuning and secondly a YIG tuned type. Varactor tuned oscillators (VTO) offer high tuning rates and low power consumption in a small, light-weight package. Whilst tuning ranges are adequate for many applications, they are smaller than can be obtained with a YTO. The limited Q of wide capacitance range varactor diodes degrades the phase noise of VTOs. By comparison the YIG-tuned oscillator (YTO) has a very wide tuning range (though not such high tuning rates as a VTO) with good linearity and excellent phase noise performance. This paper will give results on these two types of oscillator and compare them with similar circuits built using GaAs FETs or silicon BJTs.<<ETX>>

A decrease in phase noise by more than 4dB on free- running Gunn oscillators at 90 GHz is demonstrated with SSB phase noise better than -120 dBc/Hz at 100 kHz away from the carrier.

  • Generic Model for Multi-Phase Ring Oscillators

    We present a generic model for Multiple Phase Ring Oscillators (MPRO) with 2nphases, and derive equations for frequency, phase and phase error under the simplifying approach of injecting the error in a single element. Extensive Monte Carlo simulations, at transistor level, for the four and eight phase circuits, are in accordance with these assumptions. These results are validated by two prototype integrated circuits, implemented in a 130 nm CMOS technology: The first prototype, which is a standalone four phases Ring Oscillator (RO), validates the theoretical analysis concerning the non-linear model main conclusions and, the second prototype, which is an eight phase RO, incorporated as a block of an ISM receiver, validates the generic model for CRO concept.

  • An investigation into the frequency-settling time and post-tuning drift of broadband microwave varactor-tuned oscillators

    The Post-Tuning Drift (PTD) of microwave Varactor-Tuned Oscillators (VTOs) has been identified as a factor which can limit the switching speed of broadband microwave Phase Locked Loops (PLLs). This paper describes a technique developed to measure the PTD transients of VTOs to a high degree of accuracy, using an improved pulse generator and a delay-line discriminator. Detailed observations of the transients of bipolar and Gunn oscillators are shown, as plots, and discussed. A typical requirement is: to switch in frequency at 10 GHz by 250 MHz and settle to within 500 Hz of final frequency within 10 microseconds. If the VTO has large PTD, the rate of change of frequency can be too large for the loop to compensate, and long-term frequency and phase transients are seen at the PLL output.<>

  • High frequency 800 MHz oscillators

    The design and performance of tuned bipolar transistor power oscillators is presented. An efficiency of 54% was obtained with an output power of 26 dBm at 800 MHz and a noise level of -80 dBc/Hz at 10 kHz offset. The design method is an improved version of Kazimierczuk's procedure.<<ETX>>

  • Continuous Tunable Phase Shifter Based on Injection Locked Local Oscillators at 30 GHz

    Injection locking is used to achieve a continuous tunable phase shift over 280deg at 30 GHz. By locking a free running VCO at 15 GHz to an external reference source and doubling the output signal a very linear phase tuning range can be achieved. A phase noise of -117 dBc/Hz and -140 dBc/Hz at 100 KHz and 1 MHz offset frequency, respectively, have been measured. The prototype phase shifter is build on high epsivr= 10.2 RT/Duroid substrate to test later implementation in LTCC. The architecture is scalable to higher frequencies and can be made broadband by utilizing hybrids instead of T-junctions

  • CMOS Quadrature VCO Implemented With Two First-Harmonic Injection-Locked Oscillators

    This letter presents a new quadrature voltage-controlled oscillator (QVCO). The LC-tank QVCO consists of two first-harmonic injection-locked oscillators (ILOs). The outputs of one ILO are injected to the gates of the tail transistors on the other ILO and vice versa so as to force the two ILOs operate in quadrature. The proposed CMOS QVCO has been implemented with the TSMC 0.18 mum CMOS technology and the die area is 0.582 times 0.972 mm<sup>2</sup>. At the supply voltage of 1.0 V, the total power consumption is 8.0 mW. The free-running frequency of the QVCO is tunable from 5.31 GHz to 5.75 GHz as the tuning voltage is varied from 0.0 V to 1.0 V. The measured phase noise at 1 MHz offset is -120.01 dBc/Hz at the oscillation frequency of 5.31 GHz and the figure of merit (FOM) of the proposed QVCO is about -185.48 dBc/Hz.

  • Analysis of oscillators with external feedback loop for improved locking range and noise reduction

    A simple scheme for enhancing the locking/capture range and phase-noise performance of FET-based voltage-controlled oscillators (VCO's) is presented using a low-pass feedback loop from the oscillator output to the varactor tuning port. The nonlinearity of the FET provides for mixer or phase detector behavior (a self-oscillating mixer). The resulting feedback oscillator advantageously combines the principles of a conventional injection-locked oscillator (ILO) and phase-locked loop (PLL), which we refer to as an injection-locked phase-locked loop (ILPLL). The analysis suggests that the ILPLL can be designed for superior near-carrier phase-noise performance compared with conventional ILO or PLL circuits. A 10-GHz prototype was fabricated, which demonstrated a locking range more than double that of the isolated VCO injection-locking range over the same range of injected signal power.
