A multiplier circuit, including: a transistor with gate, source and drain connections adapted to accept an input signal by the transistor gate; a reference voltage source providing a DC reference voltage to the transistor drain; an inductor connected between the drain and the reference voltage source; a resistor connected in parallel to the inductor between the transistor drain and the reference voltage source; a current source providing a DC current to the transistor source; two capacitors forming a voltage divider, with the first capacitor connecting between the gate and the source and the second capacitor connecting between the source and the ground in parallel to the current source; and wherein the multiplier circuit is adapted to accept an input signal and provide as output an amplified current signal with a frequency that is double that of the input signal.
