60 GHz CMOS gain-boosted LNA with transformer feedbacked neutraliser

A 60 GHz low-noise amplifier (LNA) using standard 65 nm CMOS technology is presented. A gain of the 60 GHz amplifier was boosted by using a transformer feedbacked capacitor neutraliser. To stabilise the process variations caused by the positive feedback system, the body node of the triple well was adjusted to tune the capacitor value. The theory, simulation and measurements are presented. An imple...
