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.

Abstract: Aspects of the disclosure provide a circuit. The circuit includes a transistor configured to control energy entering the circuit from a power supply, a capacitor coupled with the transistor to store the energy that enters the circuit, and a protection circuit configured to counteract a voltage change of the transistor that is caused by a step voltage change in the power supply. In an embodiment, the protection circuit operates independent of the stored energy on the capacitor.
