Abstract
To include a first inverter that receives an input signal to output an inverted signal, a second inverter that receives the inverted signal to output a first internal signal, and a third inverter that receives the input signal and outputs a second internal signal by using the inverted signal as a power supply. According to the present invention, because a signal on one signal path is used as a power supply of an inverter included in the other signal path, phases of a pair of output signals based on the input signal can be exactly matched without adding a capacitor or a resistor for adjustment.
