Abstract
A closed loop DC-to-DC converter circuit that includes an open loop DC-to-DC converter circuit configured to provide charge on its output terminal. A voltage-controlled inverse-resistance component is coupled to the output terminal of the open loop DC-to-DC converter circuit, such that the greater the voltage differential across the component, the lower the resistance provided by the component. A feedback system provides a signal to a control terminal of the open-loop DC-to-DC converter circuit that is dependent on the current provided through the voltage-controlled inverse-resistance component. Specifically, the signal provided by the feedback system causes the open loop DC-to-DC converter circuit to generate more current on the output terminal when there is less current passing through the voltage-controlled inverse-resistance component, and less or no current on the output terminal when there is more current passing through the voltage-controlled inverse-resistance component.
