Abstract
There is disclosed an oscillator circuit comprising the first load capacitor with one electrode there of being connected with an input side of a CMOS inverter within a quartz oscillator circuit, and the second load capacitor with one electrode there of being connected with the output side of the inverter, wherein the inverter is coupled to a lower potential side via a current-limiting device, and the other electrodes of the first and second load capacitors are coupled to a lower potential side via the above-described current-limiting device. Thus, variations in the power-supply voltages synchronized with oscillation are reduced with realization of lower current consumption.
