A CMOS 110-dB%4040-kS/s programmable-gain chopper-stabilized third-order 2-1 cascade sigma-delta Modulator for low-power high-linearity automotive sensor ASICs

This paper describes a 0.35-mum CMOS chopper-stabilized switched-capacitor 2-1 cascade /spl Sigma//spl Delta/ modulator for automotive sensor interfaces. The modulator architecture has been selected from an exhaustive comparison among multiple topologies in terms of resolution, speed and power dissi...
