Abstract
A modified merged capacitor switching (MCS) scheme is proposed for the successive approximation register (SAR) analogue-to-digital converter (ADC). The conventional MCS technique previously applied to a pipelined ADC improves signal processing speed and, with use in the SAR ADC, this scheme achieves lowest switching energy among existing switching schemes. The MCS scheme achieves 93.4% less switching energy as compared to the conventional architecture.
