摘要:The invention provides an oscillator and a control method for controlling theoscillator which reliably oscillates even when the oscillator is driven at a low voltage. Anoscillator repeats a startup operation and a suspension of the startup operation by
turning on and off a switch with half a period of a Schmitt trigger oscillator circuit, until apiezoelectric oscillator circuit is put into a normal oscillation state. The oscillator thuscreates a number of opportunities of transient response allowing the oscillationamplitude of the piezoelectric oscillator circuit to grow, and reliably oscillates.
