Abstract
A 1.2V switched-capacitor sigma-delta modulator achieves 96dB peak SFDR and 84dB peak SNDR at 1 MS/s in a 0.13mum 6M1P general-purpose CMOS process. The high linearity is achieved by using high-gain op-amps and bootstrapped sampling switches. The power dissipation is 10.8mW at 64MHz clock frequency, excluding the voltage references
