Abstract :
A fully-differential zero-crossing-based 10b 26 MS/s pipelined ADC in a 65 nm CMOS process is presented. Switched-capacitor overshoot correction is compatible with the differential topology and allows faster operation. A CMFB is engaged in the coarse phase for constant common-mode. The 0.33 mm2 ADC achieves 54.3 dB SNDR with a FOM of 161 fJ/step.
