Abstract
A power-saving IC-type oscillation circuit is disclosed. It contains (a) a quartz oscillator circuit which contains an inverter and a feedback circuit: and (b) an output modulation circuit connected to an output terminal of the quartz oscillator circuit. The output modulation circuit is structured such that, after a sinusoidal wave is received from the output terminal, it will judge the level of the sinusoidal wave in a manner that when the level is high, a high state signal will be sent out to a CMOS transistor, and, when the level is low, a low state signal will be sent out. The output modulation circuit allows the CMOS transistor, which is to be driven by the oscillation circuit, to quickly move out of the power-consuming condition to thus reduce electrical current consumption.
