A self-clocked smart temperature sensor that can be fully integrated and self-contained is introduced in this paper for the first time. The sensor is based on resistive temperature sensing and time-to-digital conversion (TDC). An on-chip RC-based simple oscillator is proposed as the clock source of the sensor. The period of the proposed oscillator tracks the time output of the sensing circuit so that its variation due to RC spread does not affect the temperature sensor’s final digital output. Monte-Carlo simulations show that the sensor achieves an error within [Formula: see text]1.9/[Formula: see text]1.21[Formula: see text]C over a temperature range from 0[Formula: see text]C to 100[Formula: see text]C after two-point calibration.
