摘要

A 227 Msps 11b self-tuning analog-to-digital converter (ADC) based on time-to-digital conversion is presented. Sampled analog voltages are first converted to time by means of a voltage-to-time converter (VTC). Then a time-to-digital converter (TDC) converts the time to a digital signal. All the major blocks are self-tuned to address process, voltage and temperature (PVT) variations. The proposed ADC is implemented in the IBM 0.13 μm digital CMOS process and consumes 22 mW at 227 Msps, corresponding to 47 fJ/bit.
