PULSE SIGNAL GENERATION CIRCUIT, OSCILLATION CIRCUIT, ELECTRONIC APPARATUS AND PULSE SIGNAL GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pulse signal generation circuit, an oscillation circuit, an electronic apparatus and a pulse signal generation method that can operate over a wide voltage range while reconciling low power consumption and low phase noise.;SOLUTION: A pulse signal generation circuit 200 comprises: a pulsing section 210 supplied with a first supply voltage VDD1 that is a constant voltage to generate a first pulse signal having a first amplitude level from an AC signal input via a capacitance; and a level shift section 220 supplied with a second supply voltage VDD2 higher than the first supply voltage VDD1 to convert the first pulse signal to a second pulse signal having a second amplitude level.;COPYRIGHT: (C)2014,JPO&INPIT
