Abstract
An input circuit comprising a level-determining unit and an output unit is provided. In a first period controlled by a first enable signal, the level-determining unit receives an input signal at an input terminal of the input circuit and determines a voltage level of the input signal. The output unit is coupled to the input terminal. In the first period, the output unit outputs the input signal with the determined voltage level at an output terminal of the input circuit to serve as an output signal. In a second period following the first period, the output unit latches the determined voltage level of the input signal according to a second enable signal and outputs the input signal with the determined voltage level at the output terminal to serve as the output signal.
