Abstract :
This paper discusses the design of high-linearity analog CMOS circuits in basic digital CMOS technology, which allows only low supply voltages and has a single polysilicon layer. The key design issues are described, and illustrated with the design details of two delta-sigma ADCs. The first features a very low (1.8 V) supply voltage and a 94 dB dynamic range, while the second one contains only MOSFETs, no capacitors or resistors, and achieved 94 dB peak S/THD and SNR
