In the first part, the power amplifier adopted a neutralization topology to mitigate the intrinsic gate-drain feedback of each transistor to increase power gain and reverse isolation. The amplifier consists of three differential stages that are used transformers for impedance matching and inter-stage coupling. The 3-dB bandwidths are from 19.3 to 23.3 GHz with reverse isolation better than 60 dB. The amplifier achieves a power gain of 26.2 dB, a saturated output power of 20.6 dBm, an output 1-dB gain compression point of 17.2 dBm and a power added efficiency of 16.2%. The chip size is 1.11 mm2 with pad. In the second part, we use transmission-line transformers for the input and output matching networks. The 3-dB bandwidths are from 18.8 to 23.5 GHz with reverse isolation better than 58 dB. The amplifier achieves a power gain of 26.2 dB, a saturated output power of 20.3 dBm, an output 1-dB gain compression point of 17.4 dBm and a power added efficiency of 24.1%. The chip size is 1.11 mm2 with pad. In the third part, a wideband V-band power amplifier is implemented by adopting wideband matching network technique. The V-band power amplifier with wideband in tsmcTM 90-nm CMOS Technology achieves a power gain of 17.8 dB, a saturation output power of 11.4 dBm, an output power at 1-dB gain compression point of 7.2 dBm, and a power added efficiency of 4.4%. The 3-dB bandwidths are from 47.2 to 67 GHz. The chip size is 0.57 mm2 with pad.
