Computer Aided Design of Monolithic Microwave and Millimeter Wave Integrated Circuits and Subsystems.

摘要

The objectives of this research are to develop analytical and computer-aided design techniques for monolithic microwave and millimeter-wave integrated circuits (MMIC & MIMIC) and subsystems and to design and fabricate those ICs. Emphasis was placed on heterojunction-based devices, especially the High Electron Mobility Transition (HEMT), for both low-noise and medium-power microwave and millimeter-wave applications. Circuits to be considered include monolithic low-noise amplifiers, power amplifiers, and distributed and feedback amplifiers. Interactive computer aided design programs have been developed, which include large-signal models of InP MISFETs and InGaAs HEMTs. Further, a new unconstrained optimization algorithm-POSM has been developed and implemented in the general-purpose Analysis and Design program for Integrated Circuit (ADIC) for assistance in the design of large-signal non-linear circuits.
