Abstract
A time-to-digital converter (TDC) with a 2.5µs input range and an accuracy of 100 ps has been designed. According to test results the single-shot resolution of the TDC is 30 ps (rms) at the clock frequency of 100 MHz. The linearity error is less than ±10 ps in the input time range 10 ns to 2.5µs. The temperature drift of the TDC was measured to be 100 ps in the temperature range -30°C to +60°C.
