Energy and area-efficient tri-level switching procedure based on half of the reference voltage for SAR ADC

Abstract

An energy-efficient tri-level switching scheme based on half of the reference voltage (Vref ) is proposed for the successive approximation register (SAR) analogue-to-digital converter (ADC). With respect to the set-and-down switching scheme, the common-mode voltage variation at the input of the comparator reduces. By using Vref/2, the switching energy and… (More)
