Title:
OUTPUT SIGNAL GENERATION DEVICE, SEMICONDUCTOR DEVICE AND OUTPUT SIGNAL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/112509
Kind Code:
A1
Abstract:
This output signal generation device includes: a phase adjustment unit that generates an output signal on the basis of an input signal and is capable of executing an adjustment operation of setting the phase difference between the input signal and the output signal to a predetermined value; a holding unit that holds a reference voltage; a comparison voltage generation unit that generates a comparison voltage that is dependent on a power supply voltage; and a control unit that intermittently compares the comparison voltage with the reference voltage held in the holding unit, causes the phase adjustment circuit to execute the adjustment operation when the comparison result satisfies a predetermined condition representing a variation in the power supply voltage, and changes the reference voltage held in the holding unit in accordance with the power supply voltage.
