Abstract :
A 14-b, 0.1ps resolution interpolating coarse - fine Time-to-Digital Converter (TDC) has been developed in 45nm CMOS technology. It is based on an asynchronous buffer delay line and an RC delay line. A lookup-table (LUT) based calibration scheme was developed to correct non-linearities due to PVT variations.
