Abstract
An integrated digital CMOS time-to-digital converter with 92 ps LSB width and 50 ps single shot resolution has been designed. The measurement is based on a counter and a novel two step parallel interpolation that uses only 32 delay elements to provide 128 LSBs in the interpolator. The current consumption of the circuit is <20 mA from a single +5 V supply
