Abstract :
This letter presents a CMOS amplifier with 22 GHz 3-dB bandwidth ranging from 86 to 108 GHz. The amplifier is implemented in 90 nm mixed signal/radio frequency (RF) CMOS process using three-stage cascode RF NMOS configuration. It achieves a peak gain of 17.4 dB at 91 GHz from the measured results. To our knowledge, this is the highest frequency CMOS amplifier reported to date.
