A fully differential amplifier has been realized in 65 nm CMOS technology, which has demonstrated 20 dB peak gain, over 10 dB gain from 128-157 GHz, and 40 GHz positive gain range from 126 to 166 GHz. By using cascode architecture with high bulk voltage tied to the cascode devices in deep-Nwell, the amplifier ensures stability and can use 2 V supply reliably. By inserting a π-matching network between cascode devices, it broadens the amplifier working range. This amplifier occupies 0.05 mm2 chip… CONTINUE READING
