  • Abstract
    A 2-1 MASH delta-sigma modulator (DSM) was fabricated using a 90nm CMOS technology. Operating at 6.25 MHz clock rate, this chip consumes 860 μW under a 1 V supply. The over-sampling ratio is 128, and the signal-bandwidth is 24.4 kHz. This chip achieves a performance of 88 dB SNDR and 90 dB SNR. Its dynamic range is 100 dB. The chip area is 0.44 mm2.
