Abstract

The effects of comparator input common-mode voltage Vcm are analyzed in this paper. The analysis clearly shows a trade-off in the choice of Vcm in terms of offset, noise, power and speed. Based on the analysis, an energy efficient SAR ADC switching technique is proposed with less Vcm variation and better linearity compared with the widely used monotonic switching technique. Both the simulation results and prototype measured results match with the analysis.
