Abstract
An apparatus includes a transistor with a control terminal, a first current terminal, and a second current terminal. The apparatus also includes a charge pump coupled to the control terminal of the transistor via a first and second paths. The first path comprises a first resistor and the second path comprises a second resistor in series with a diode. The first resistor has a higher resistance value than the second resistor.
