This is the core of the book, covering the design of individual stages.
As the industry pushes into 30 GHz, 60 GHz, and beyond (for 5G and radar), standard microwave theory becomes harder to apply directly to ICs. This textbook is one of the few that provides dedicated chapters on mmWave design, including:
The book starts with a brutal reality check: a transistor is not an amplifier; it is a collection of parasitic capacitances and resistances. Voinigescu provides rigorous derivations of current-gain cutoff frequency (fT) and maximum oscillation frequency (fMAX). He explains how to extract these figures from a 1-port or 2-port S-parameter measurement. Crucially, he links these device metrics to achievable circuit bandwidths—showing why you need an fMAX roughly 3-5x higher than your target operating frequency.
If you have acquired the highfrequency integrated circuits sorin voinigescu pdf, do not just read it like a novel. Follow this methodology:
