Abstract
There is disclosed an oscillator circuit in which the first capacitor is connected between the input side of a CMOS inverter in a quartz oscillator circuit and a higher potential side, the second load capacitor is connected between the input side of the inverter and a lower potential side, the third load capacitor is connected between the output side of the inverter and the higher potential side, and the fourth load capacitor is connected between the output side of the inveter and the lower potential side, so that variation in amplitudes of the voltage sources synchronized with the oscillation can be reduced with the realization of lower current consumption.
