Abstract :
A broadband monolithic microwave active inductor composed of two FETs and a resistor is proposed. The most significant innovation of the active inductor is considered to be a novel circuit structure which suppresses stray capacitance to yield a much higher-frequency operating range than a spiral inductor. The inductor is small and independent of the inductance value. The FET-oriented configuration allows a denser chip circuitry packing. A 0.1-10-GHz miniaturized wideband amplifier realized using the active inductors is described.<>
