Abstract: An input receiver controls an offset voltage by using an output feedback signal to improve a sense speed. The input receiver includes a pre-amplifier that controls an offset voltage in response to a feedback signal and amplifies an input signal with reference to a reference voltage. A sense amplifier amplifies an output signal and an inverted output signal of the pre-amplifier in response to a clock signal. A latch circuit latches an output signal and an inverted output signal of the sense amplifier. An inversion circuit uses the reference voltage as a power supply voltage and inverts an inverted output signal of the latch circuit. In addition, an output signal of the inversion circuit is supplied as the feedback signal. Alternatively, the output signal of the latch circuit may be directly supplied to the pre-amplifier as the feedback signal while not using the inversion circuit.
