Two minimum component CCII-based RC oscillators
1987 Edition, Volume 34, August 1, 1987 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Two minimum-component RC-sinusoidal oscillator circuits using current conveyors are proposed. Each circuit uses a single current conveyor, two resistors, and two capacitors. The two circuits enjoy low sensitivity characteristics.

Harmonic RC-oscillators with automatic amplitude control system
2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This article is devoted to the development and investigation of sine wave RC oscillator with twin T-bridge (TT-bridge) band-stop filter in the negative feedback circuit and automatic amplitude control system. We investigated the automatic amplitude control system, its effect on the...

An RC Oscillator With Comparator Offset Cancellation
2016 Edition, Volume 51, August 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A fully-integrated 18.5 kHz RC time-constant-based oscillator is designed in 65 nm CMOS for sleep-mode timers in wireless sensors. A comparator offset cancellation scheme achieves 4× to 25× temperature stability improvement, leading to an accuracy of ±0.18% to ±0...

Techniques of Temperature Compensation in a RC Oscillator
2007 Edition, Volume 2, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a technique of temperature compensation for a low power RC oscillator that due to design considerations is biased with a PTAT current. The RC oscillator was implemented in a 0.25 μm technology and the overall performance obtained over the whole...

Minimum achievable phase noise of RC oscillators
2005 Edition, Volume 40, March 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To make RC oscillators suitable for RF applications, their typically poor phase-noise characteristics must be improved. We show that, for a given power consumption, this improvement is fundamentally limited by the fluctuation-dissipation theorem of thermodynamics. We...

Statistical circuit design: A Monte Carlo tolerance analysis of the integrated, single-substrate, RC, touch-tone® oscillator
1971 Edition, Volume 50, April 1, 1971 - AT&T Corp.

Monte Carlo tolerance analysis has proven to be an effective tool in evaluating the sensitivity of a circuit design to manufacturing tolerances and environmental changes. Such an analysis involves repetitively "constructing" samples of the design in the computer, randomly selecting...

A micropower RC oscillator chip for consumer ASIC applications
1991 Edition, January 1, 1991 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A micropower CMOS RC oscillator with a frequency of 32 kHz for low-voltage biomedical applications has been designed and tested. The supply voltage range and current consumption of the unit are 2.5-3.5 V and about 2 mu A, respectively. It was found that the temperature drift of...
