Abstract
Aspects of the disclosure provide a circuit. The circuit includes a depletion mode transistor coupled to a power supply and a current path coupled with the depletion mode transistor in series to provide a current to charge a capacitor. The current path has a first resistance during a first stage, such as when the circuit initially receives power, and has a second resistance during a second stage when the capacitor is charged to have a predetermined voltage level.
