Abstract
An input receiver capable of sensing and amplifying an external signal having a very small swing input signal. The input receiver comprises a clock sampled amplifier for receiving a clock signal and a reference signal, respectively, in response to a first state of a clock signal and a delayed sampling clock signal, and for amplifying and sampling the voltage difference between the external signal and the reference signal, respectively, in response to a transition of the clock and delayed sampling clock signals to a second state; and a pulse generator for pre-charging a power source voltage and selectively pulling down the pre-charged signals to produce a pulse signal, in response to the second state of the delayed sampling clock signal and outputs of the clock sampled amplifier.
