Abstract :
A 0.18mum CMOS 12b 100kS/s successive approximation ADC is presented. The entire ADC consumes 25muW from a 1V supply and achieves an SNDR of 65dB. Its sampling rate can be scaled, yielding linear power savings. Efficiency of the comparator is increased by an offset compensating latch, while noise performance and common-mode rejection are improved by a modified capacitor network
