Radio-frequency/direct-current converter

A radio-frequency/direct-current (RF/DC) converter, operable to receive a high-frequency and high-power RF signal and convert to a DC power, the RF/DC converter comprising:

• an RF signal receiving end;
• a potential reference end;
• an output end;
• a first field-effect transistor (FET), comprising a first source connected to the RF signal receiving end, a first gate and a first drain;
• a second FET, comprising a second source connected to the RF signal receiving end, a second gate and a second drain;
• a third FET, comprising a third source connected to the potential reference end, a third gate connected to the first gate and the second drain, and a third drain connected to the second gate and the first drain;
• a fourth FET, comprising a fourth source connected to the potential reference end and the third drain, a fourth gate connected to the first drain, and a fourth drain connected to the first gate;
• a fifth FET, comprising a fifth source connected to the output end, a fifth gate connected to the second drain, and a fifth drain connected to the second source;
• and
• a sixth FET, comprising a sixth source connected to the output end, a sixth gate connected to the first drain, and a sixth drain connected to the second source.
