A 1 V 10.7 MHz switched-opamp bandpass /spl Sigma//spl Delta/ modulator using doublesampling finite-gain-compensation technique

摘要

A 1 V 10.7 MHz switched-opamp bandpass /spl Sigma//spl Delta/ modulator uses modified double-sampling finite-gain-compensation. In a standard 0.35 /spl mu/m CMOS process at 1 V supply, the modulator achieves 42.8 MHz effective sampling frequency with 42.3 dB peak SNDR while dissipating 12 mW in 1.3 mm/sup 2/ chip area.
