Abstract:
A diode circuit having a passive element property, and an impedance modulator and a direct current (DC) source that use the diode circuit are provided. The diode circuit includes a first diode that generates a predetermined DC and alternating currents (AC) when a radio frequency (RF) signal is applied; and a DC path that is connected in parallel to the first diode, forms a predetermined loop and circulates the DC current within the loop. The DC path includes an inductor or an LC parallel resonator. The DC path includes a second diode that is disposed in the opposite direction to the first diode and connected to the first diode in parallel. The present invention can relieve difficulty in designing an RF circuit.
