1. A zero bias power detector, comprising:

  • a zero bias diode, which outputs a rectifying signal according to a wireless signal; and

    an output boost circuit, comprising;

    a zero bias transistor, wherein the zero bias transistor, coupled to the zero bias diode, is used for enhancing the rectifying signal, wherein the control terminal of the zero bias transistor is coupled to the zero bias diode, a first terminal of the zero bias transistor is directly connected to only a loading, and a second terminal of the zero bias transistor is directly connected to only a ground terminal.
