Using nonlinear systems techniques, we analyze the stability properties and synchronization conditions for ring oscillator circuits, which are essential building blocks in digital systems. By making use of its cyclic structure, we investigate local and global stability properties of an n-stage ring oscillator. We present a sufficient condition for global asymptotic stability of the origin and obtain necessity if the ring oscillator consists of identical inverter elements. We then give a synchronization condition for identical interconnected ring oscillators.

A new RF switched capacitor bandpass filter and its command circuit made up of a ring voltage controlled oscillator with 'XOR' gates are proposed. Implemented in a standard 0.35 m CMOS technology, this circuit is intended to be used in a subset of professional mobile phone applications . Experiments carried out on a prototype show a tunable center frequency range of 260 MHz [240-500 MHz], with a quality factor that can be as high as 300.

“…High integration capability of ring oscillators has made them an integral part of many digital and analog systems [2]. These building blocks are used as beating heart of applications such as disk drive read channels [3], clock recovery circuits for serial data communications [4]. Stable frequency is imperative in order to minimize interference in adjacent frequency bands, as far as many communications applications are concerned [5].…”

This paper presents a CMOS voltage controlled ring oscillator (VCO) with temperature compensation circuit suitable for low-cost and low-power wireless sensing applications. To operate at low frequency, a control voltage generated by a CMOS bandgap reference (BGR) is described and the measurement results of the fabricated chips are presented. The output voltage of the reference is set by resistive subdivision. In order to achieve small area and low power consumption, n-well resistors are used. This design features a reference voltage of 1V. The chip is fabricated in AMS 0.35 µm CMOS process with an area of 0.032mm 2 . Operating at 1.25V, the output frequency is within 200±l0kHz over the temperature range of -25°C to 80°C with power consumption of 810µW.
