    摘要: Rectifier circuit (600) comprising a pair of input terminals (614, 616), a pair of output terminals (654, 656), and a first circuit (601) interconnecting the pair of input terminals (614, 616). The first circuit (601) comprises an energy storing element (34) and a rectifier bridge (642), wherein the rectifier bridge comprises at least one controllable switching element (645, 647) per bridge branch. An output of the rectifier bridge (642) supplies the pair of output terminals (654, 656) and wherein the at least one controllable switching element per bridge branch is configured to provide a temporary conducting path via the rectifier bridge which substantially bypasses the pair of output terminals (654, 656) and which substantially short-circuits a second circuit (602) comprising the energy storing element (34), the pair of input terminals (614, 616), and an energy source (12) connectable to the pair of input terminals. A converter for synchronized switch harvesting on inductor comprising such a rectifier circuit and a method for rectifying an electrical current generated by an energy source are also described.

    摘要: A non-quasistsic MOS rectifier circuit (530) uses a bridge-rectifier configuration using four organic PMOS transistors (Ml, M2, M3 and M4), an antenna coil (532) to induce a differential input signal, and an output capacitor (534) for filtering the rectified output signal. The VSS or ground-connected transistors are diode-connected with the gate connection on the coil side of the transistor channel. The VDD-connected transistors have gates connected to the opposing VDD-connected transistor source that is connected to the coil (532). This configuration results in full-wave rectification. The gates are all connected to the coil and thereby become part of of the capacitance of the radio frequency parallel resonant network. The transistor gates are then switched at the rate of the radio frequency signal with no delay relative to the coil voltage, Operation of the organic transistors is based on non-quasistatic behavior of the transistor. Non-quasistatic operation results in rectification at a frequenct much higher than the quasistatic limit of transistor unity gain bandwidth.
