Abstract: A time detection circuit and a time detection method are provided. The time detection circuit includes an input signal processor and a time signal amplifier. The input signal processor receives a first input signal and a second input signal, calculates a time difference value between the first input signal and the second input signal, adjusts the time difference value by comparing the time difference value with a set reference value, and provides the adjusted time difference value. The time signal amplifier receives the adjusted time difference value, and amplifies the adjusted time difference value to generate an amplified time signal. The time signal amplifier operates in a linear operation region between a first time value and a second time value, and the set reference value is set according to the first time value and the second time value.
