An active diode including a NMOS transistor having a source terminal, a drain terminal, a gate terminal and a back gate terminal, where the source terminal is connected to the back gate terminal and forms the anode terminal of the active diode, and the drain terminal forms the cathode terminal of the active diode. The active diode further includes an offset bias voltage source having a first terminal and a second terminal; and an amplifier having a non-inverting input terminal and an inverting input terminal, and an output terminal, where the inverting input terminal is connected to the drain terminal of the transistor, the non-inverting input terminal is connected to the first terminal of the offset bias source, the output terminal is connected to the gate terminal of the transistor, and the second terminal of the offset bias source is connected to the source terminal of the transistor.
