A Zero-Crossing-Based 8b 200MS/s Pipelined ADC

A zero-crossing-based 8b 200MS/S pipelined ADC is implemented in a 0.18 mum CMOS process. It uses dynamic zero-crossing detectors and digital FFs that replace the functions of opamps and comparators. The ADC draws no static current. The power consumption is 8.5mW. The FOM is 0.51pJ/step
