Abstract

This manuscript examines in detail the mechanisms and behavior of flicker noise in switched biased MOS transistors. Firstly, the PSD of a DC biased transistor is deduced using only Shockley-Read-Hall (SRH) statistics and the autocorrelation formalism. Then the analysis is extended, by means of simulations and using simple physical hypotheses, to a switched bias condition. The results allow explaining several reported experimental measurements. Particularly, the 1/f form of flicker noise at very low frequencies is observed in simulations; this behavior is not correctly addressed by previously reported noise models of switched MOSFET.
