Abstract
An active inductor circuit implemented in sub-micron CMOS semiconductor technology is usable at gigaHertz frequencies and includes an input node, a non-inverting transconductor circuit comprising a differential pair of NMOS transistors connected to the input node, an inverting transconductor circuit comprising an NMOS transistor connected to an output node of the non-inverting transconductor circuit and connected to the input node in a gyrator feedback configuration. Varactors coupled to the transconductor circuits tune the frequency and Q of the active inductor circuit.
