Summary:The invention provides an oscillator circuit that reduces the dependence of an oscillation frequency on a power supply voltage. When a first charging and discharging circuit completes its discharge, a terminal voltage of a first capacitor of the first charging and discharging circuit is initialized to a power supply voltage and simultaneously a second charging and discharging circuit starts its discharge. Then, when the second charging and discharging circuit completes its discharge, a terminal voltage of a second capacitor of the second charging and discharging circuit is initialized to the power supply voltage and simultaneously the first charging and discharging circuit starts its discharge. The first and second charging and discharging circuits alternately repeat the initialization and the discharge, and the discharge is always started from the power supply voltage.
