Abstract
A high energy-efficiency tri-level switching scheme for successive approximation register converters (SAR ADCs) is presented. The most significant bit-splitting digital to analogue converter and the least significant bit-down technique are combined in this work. The proposed scheme achieves 99.76% saving in switching energy and 75% area reduction compared with the traditional scheme. Besides large switching energy saving, the common mode voltage keeps constant except the LSB conversion, which reduces the dynamic offset of the comparator.
