Abstract :
This paper describes a low-power low-distortion pipeline ADC with 1.0V supply voltage. A cascade amp-sharing architecture and capacitor coupling class-AB amplifier are proposed for low-power dissipation under high-speed sampling. The capacitance coupling S/H stage suppresses the distortion caused by the insufficient gate-source voltage of sampling switches due to a low supply voltage. According to H-SPICE simulation results, the 10b 125MSample/s ADC in 90nm digital CMOS process achieves SNDR of 56dB with a power dissipation of only 21mW
