Abstract:
1. A rectifier circuit comprising: a depletion mode semiconductor having an output connected to a rectified signal output node of the rectifier circuit; a hot carrier semiconductor diode having a cathode connected to a source node of the depletion mode semiconductor and an anode connected to a gate node of the depletion mode semiconductor; and an alternating current (AC) input node that is connected to the anode of the hot carrier semiconductor diode and the gate node of the depletion mode semiconductor and that is configured to receive an AC input signal, wherein when a first half cycle of the AC input signal is applied to the AC input node, a voltage drop between the AC input node and the rectified signal output node comprises a sum of a diode forward biased voltage drop and a voltage drop due to a source to drain resistance of the depletion mode semiconductor.
