Abstract
The present disclosure relates generally to digital microphone and other sensor assemblies including a transduction element and a successive-approximation (SA) quantizer configured to reuse a digital code generated for a prior sample period for a current sample period when a reuse condition is satisfied. The SA quantizer does not regenerate a new digital code for the current sample period when the digital code generated for the prior sample period is used thereby reducing power consumption.
