ABSTRACT:
A full-wave rectifying device having an amplitude modulation function receives energy emitted from a transceiver via an external antenna and then rectifies it into a DC power source for use by an IC device. One embodiment includes a positive half-wave diode and a negative half-wave diode, whose anodes are connected to ends of the antenna and whose cathodes are formed by the N-substrate. A rectifying NMOS transistor has its gate and drain coupled to ground and its source connected to the anode of the negative half-wave diode. A positive half-wave switch is coupled between the source and bulk of the rectifying NMOS transistor. A negative half-wave switch is coupled between the drain and bulk of the rectifying NMOS transistor. A modulating NMOS transistor has its source and bulk coupled to ground, its drain coupled to the anode of the positive half-wave diode, and its gate used to receive a modulated signal transmitted to the gate of the modulating NMOS transistor during a positive half-wave rectification for modulation. A bypass NMOS transistor has its bulk and source connected to ground, its gate coupled to the anode of the negative half-wave diode, and its drain coupled to the anode of the positive half-wave diode. A capacitor is coupled between the cathodes of the positive and negative half-wave diodes and the ground reference point to store electrical energy for use by the IC.
