Power-efficient compute-in-memory analog-to-digital converters

Abstract:

A time-multiplexed group of MAC circuits for a machine learning application is provided in which at least one MAC circuit in the time-multiplexed group also functions as a capacitive-digital-to-analog converter (CDAC) within a successive approximation analog-to-digital converter (ADC). A comparator in the ADC is shared by the time-multiplexed group of MAC circuits.
