ABSTRACT:
A stable, low power consumption signal detecting circuit may include: a delay circuit, which receives a base clock signal and generates multiple versions thereof having time delay relationships thereto, respectively; dual amplifiers, which detect valid ones of input signals by comparing the input signals with reference voltage signals in response to the multiple versions of the base clock signal, respectively; a combining unit, which generates a combination signal in response to output signals of the dual amplifiers; and a sampling circuit, which samples the combination signal according to the base clock signal and generates an output signal.
