ABSTRACT:
A switched capacitor, integrated circuit employing at least one non-linear capacitor charged and discharged in response to a reference frequency includes a first conductive device for charging the non-linear capacitor to the supply voltage in response to one polarity of the reference frequency, and a second conductive device for discharging the non-linear capacitor in response to the opposite polarity of the reference frequency to a voltage level opposite that of the voltage source minus the threshold voltage of a third conductive device in the discharge path. Preferably, a pair of non-linear capacitors are employed, each being charged on alternate half cycles of the reference frequency, and the non-linear capacitors are accumulator capacitors. The circuit also include means for rapidly initiating the charging and discharging of said capacitors and for precluding changes in the state of charge or discharge thereof due to parasitic diodes in the circuit.
