چکیده :

Low dynamic range (DR) and the sensitivity to process variations and mismatch are the two known issues of the time amplifiers (TA) which have been utilized in deep sub-micron implemented time-to-digital converters (TDC). To alleviate these problems, a 2× time amplifier with a wide input time difference range is proposed in 65 nm CMOS technology which employs a new compensation technique based on time-to-current conversion. This compensation method maps the input time to an appropriate current value injecting into the conventional 2× TA. Simulation results demonstrate a 400 ps input time range with less than 10% gain error while the TA has the maximum delay of 120 ps. Monte-Carlo simulation shows less than 9% standard deviation at inputs higher than 20 ps for the TA gain.
