摘要：Disclosed is an oscillator in which current consumption relating to oscillation isreduced. The oscillator comprises: an amplifier to an input and output of which apiezoelectric oscillator and a feedback resistor are connected in parallel, and which is

constituted by a CMOS logic inverter circuit; and a control circuit, which is constituted by aCMOS logic circuit, for clamping input/output levels of the amplifier and halting

oscillation before oscillation start-up, unclamping the input/output levels at beginning ofoscillation start-up and supplying a pulse signal to an output terminal of the amplifier aprescribed period of time after the beginning of oscillation start-up.
