A high resolution time detecting apparatus using interpolation and a time detecting method using the same are provided. The time detecting apparatus includes a delayer which generates delayed signals by sequentially delaying a reference signal using a plurality of delay elements, a latch unit which outputs latch signals using the delayed signals, and an interpolation unit which outputs interpolated signals using input and output signals of the delay elements. As a result, a high resolution TDC using an interpolation and a time detecting method using the same provide improved performance of digital PLL, high resolution digital signal output at a low power consumption, and controlled circuit size.
