Time domain ADC using pulse shrinking TDC

In this paper, a ADC using pulse shrinking TDC is proposed. The proposed ADC include a Pulse forming circuit, Pulse shrinking TDC and a compatible Counter. Initially, input voltage is converted to a proportional time pulse and then digitized using Time to Digital Converter (TDC). We present a fully-integrated Time-to-Digital Converter based on cyclic pulse-shrinking design. The whole setup is implemented and simulated in standard 0.12um ASIC platform.
