Active diode circuit including n-type transistors

Abstract

Some embodiments include an apparatus including a supply node; a bootstrap capacitor including first plate, and a second plate coupled to a circuit path, the circuit path coupled to a ground connection; and an active diode circuit. The active diode circuit includes an n-type transistor and a comparator. The n-type transistor includes a first terminal coupled to the supply node, a second terminal coupled to the first plate of the bootstrap capacitor, and a gate. The comparator includes a first input path coupled to the supply node, a second input path coupled to the first plate of the bootstrap capacitor, and an output node coupled the gate of the n-type transistor.
