“…However, the degenerated inductor used in this type of amplifier can reduce its gain, which is only acceptable at these frequencies due to the high intrinsic transistor gain. As the frequency increases, such as in the V-band, E-band, and W-band, the common-source amplifier is often replaced by a cascode amplifier, which provides higher gain per stage [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”
