Abstract :
A four channel, self-calibrating, High Resolution Time to Digital Converter (HRTDC) with an RMS error of 35 ps over a dynamic range of 3.2 μs has been developed. Its architecture is based on an array of delay locked loops and an 8-bit coarse time counter driven by an 80 MHz reference clock. Time measurements are buffered in two time registers per channel followed by a common 32 words deep read-out FIFO. The HRTDC has been built in a 0.7 μm CMOS process using 23 mm2 of silicon area
