Abstract
This experimental switched-capacitor /spl Sigma//spl Delta/ modulator achieves 92 dB dynamic range for a signal bandwidth of dc to 25 kHz while operating from 1.8 V supply. The supply voltage is consistent with the end-of-life of two battery cells in series. The fully-differential circuit has been integrated in a 5 V, 1.2 /spl mu/m CMOS technology with poly-n/sup +/ capacitors.
