1. An apparatus, comprising:
a first transistor having a first gate, a first source, and a first drain, in which the first source is coupled to a first voltage terminal;
a second voltage terminal;
a resistor coupled between the first gate and the second voltage terminal;
a second transistor having a second gate, a second source, and a second drain, in which the second gate is coupled to the first drain, and the second source is coupled to the first voltage terminal;
a third transistor having a third gate, a third source, and a third drain, in which the third drain is coupled to the second drain, and the third source is coupled to a ground terminal; and
a capacitor coupled between the first drain and the third gate.
