Abstract
A semiconductor device includes a detector that receives an input signal whose characteristics fluctuate depend on the standby mode state, compares the input signal amplitude with a specific threshold amplitude, and outputs a detector output signal that shows whether or not the amplitude of the applicable input signal is above the specified threshold amplitude; and an intermittent operation control circuit that along with receiving the detector output, also receives a first signal showing which mode among the multiple standby mode states is in, and sets the detector to the continuously on (enable) mode state when the input signal is above the specified threshold amplitude, and in all other cases intermittently operates the detector depend on the characteristics of the input signal in the mode shown by the first signal.
