14 Aug 1989TL;DR: In this paper, a method for finding an equivalent noise bandwidth for a regenerative detector which allows the accurate prediction of period jitter with no fitted parameters is reported, where the model includes the time constant of the amplifier around which the detector is built, even for predicting the oscillator's noise free period.
Abstract: A method for finding an equivalent noise bandwidth for a regenerative detector which allows the accurate prediction of period jitter with no fitted parameters is reported. The analysis reported is new in several ways. First, the model includes the time constant of the amplifier around which the detector is built ( tau /sub OUT/), even for predicting the oscillator's noise-free period. With tau /sub OUT/ nonzero, the delay between each threshold-crossing and the detector's response lengthens the oscillator's period by the excess period (about four times the delay). Simulations of an emitter-coupled oscillator (ECO), in excellent agreement with measurements, show that the excess period is roughly proportional to tau /sub OUT//sup 2/3/. Second, the noise analysis avoids small-signal bandwidths by using the pulse sensitivity. >

19 Jan 1979TL;DR: Within a relaxation oscillator of the type having a capacitor that is recurrently being charged from a current source and discharged through a silicon controlled rectifier upon reaching a voltage threshold thereacross, a switch is disposed to interrupt current flow through the SCR in response to the capacitor being discharged to a predetermined level as discussed by the authors.

TL;DR: The average time to synchrony for a chain of n oscillators, is proportional to n/sup p/, where p is a parameter dependent value that is obtained experimentally and is observed to be less than 0.5.
Abstract: Motivated by reports of synchronous neural activity in the brain, and the use of relaxation oscillators as models of neuronal activity, we study synchronization in chains of locally coupled relaxation oscillators. We find that the average time to synchrony for a chain of n oscillators, is proportional to n/sup p/, where p is a parameter dependent value that is obtained experimentally and is observed to be less than 0.5.
