Noise in relaxation oscillators
Abstract
Relaxation oscillator noise may be described by a single, normalized equation which allows its timing jitter to be predicted. The value of this equation lies in its linearization of the nonlinear regenerative waveforms of the oscillator, and also suggests those circuit topologies promising low jitter. This theory is presently confirmed through experimental measurement of practical oscillators, as well as through its use in the development of a prototype low noise oscillator with a measured jitter of 1.5 ppm rms.
