A New Solution to Analysis of CMOS Ring Oscillators

New equations are proposed for frequency and amplitude of a ring oscillator. The method is general enough to be used for all types of delay stages. Using exact largesignal circuit analysis, closed form equations for estimating the frequency and amplitude of a high frequency ring oscillator are derived as an example. The method takes into account the effect of various parasitic capacitors to...

Synchronization of Subthreshold-cmos Chaotic Oscillators

This paper reports on the design and chip measurements from synchronous coupled chaotic oscillators operating in subthreshold CMOS. Each uncoupled oscillator is autonomous and generates chaotic signals with three state variables. For commensurate bandwidth, the subthreshold designs utilize currents and capacitors over 200 times smaller than above threshold realizations. The reduced size makes s...

Phase Noise in CMOS Differential LC Oscillators

An analysis of phase noise in differential cross-coupled tuned tank voltage controlled oscillators is presented. The effect of active device noise sources as well as the noise due to the passive elements are taken into account. The predictions are in good agreement with the measurements for different tail currents and supply voltages. The effect of the complementary cross-coupled pair is analyz...

Simple Chaotic Circuit Using CMOS Ring oscillators

In this study, a chaotic circuit suitable for an integrated circuit is proposed. The circuit consists of two CMOS ring oscillators and a pair of diodes. By using a simplified model of the circuit, the mechanism of generating chaos is explained and the exact solutions are derived. The exact expressions of the Poincaré map and its Jacobian matrix make those possible to confirm the generation of c...

CMOS OTA - C High - Frequency Sinusoidal Oscillators

Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA’S dominant nonidealities. Building blocks are presented for amplitude control, both by AGC schemes and by limitation schemes. Experimental results from 3and 2-pm CMOS (...
