✦ Synopsis

A design methodology for simulated MMIC inductors is presented. While audio-frequency realizations of such circuits are built using relatively imperfection-free gyrators terminated in lossless capacitors, our microwave implementation necessarily allows the specification of tables of s-parameters for the transistors in the network, along with detailed models for the passive MMIC components. Our method, in computer simulation, has realized a 5-nH inductance over 1.5-2.5 GHz by terminating a nonideal transistor gyrator in a special compensating RLC one port, which itself may be designed using readily available CAD tools. Such simulated inductors have important application in microwave active filters.
