1. A circuit comprising:
a first capacitor;
a first current control device configured to provide an input current to the first capacitor during a positive cycle of an alternating current (AC) input voltage;
a second capacitor having first and second terminals, the second capacitor configured to store a charge;
a switch coupled between the first terminal of the second capacitor and a ground terminal, wherein the switch is configured to discharge the second capacitor during the positive cycle of the input voltage, providing a capacitor current, responsive to the stored charge in the second capacitor; and
a second current control device configured to provide current to the first capacitor during the positive cycle of the input voltage, wherein the first capacitor is configured to store a charge responsive to the input current and the capacitor current.
