Abstract
A time-to-digital converter is provided. The time-to-digital converter comprises an oscillator controller, an invertible oscillator and a measurement circuit. The oscillator controller receives a start signal and a stop signal and outputs a mode signal. The invertible oscillator is electrically connected with the oscillator controller for receiving the mode signal. The oscillation direction of the invertible oscillator is inverted according to the mode signal, and the invertible oscillator outputs plural delay signals. The measurement circuit is electrically connected with the invertible oscillator for receiving the plural delay signals. The measurement circuit receives a sampling signal, samples the plural delay signals in accordance with the sampling signal, and outputs an output signal.
