Abstract
This paper describes the first gigasample rate time-based Nyquist analog-to-digital converter (ADC), consisting of a voltage-to-time-converter (VTC) followed by a time-to-digital- converter (TDC). After tuning, the 3-bit 2.5GS/s ADC designed in 90nm CMOS is measured to have an effective number of bits (ENOB) greater than 2.1 up to the Nyquist frequency. The power consumption, not including the TDC output drivers, is 12.1 mW.
