Most textbooks define cut-off frequency (( f_T )) trivially. Voinigescu dedicates Chapter 2 to extracting ( f_T ) and maximum oscillation frequency (( f_max )) from S-parameters measured on a 40nm or 28nm CMOS process. He provides actual measured data plots that you won't find in any other textbook.

The book’s legacy is secure because it captures the turning point where By showing that a 65nm CMOS transistor could be biased to work at 200 GHz, Voinigescu effectively predicted the single-chip radios we have today. Most textbooks define cut-off frequency (( f_T )) trivially

High-frequency ICs are critical components in modern communication and radar systems. The design and implementation of high-frequency ICs pose significant challenges, but researchers like Sorin Voinegescu have made significant contributions to the field. This report provides an overview of high-frequency ICs, their applications, challenges, and design techniques. Further research and development are needed to push the limits of high-frequency ICs and enable new applications.
