0-60 GHz in four years: 60 GHz RF in digital CMOS

In early 2001, most researchers were focusing on the spectrum from 1-5 GHz, with a few isolated research groups pushing circuits up to 24 GHz. The suggestion to exploit 60 GHz with CMOS seemed comic to some but the availability of nearly universal unlicensed spectrum was the obvious motivation. The Berkeley Wireless Research Center has succeeded in developing an extended BSIM3 model, a library of active and passive devices, and demonstrated the world fastest CMOS amplifier at 104 GHz.
