The three-stage fully differential amplifier with capacitive neutralization is fabricated in 40 nm CMOS provided by TSMC. Measurement results show that the D-band amplifier obtains a peak gain of 9.6 dB over a -3 dB bandwidth from 138 GHz to 164.5 GHz. It exhibits an output 1 dB compression point (OP1dB) of 1.5 dbm at the center frequency of 150 GHz. The amplifier consumes a low power of 27.3 mW from a 0.7 V supply voltage while its core occupies a chip area of 0.06 mm2. %N 2 %V 8 %D 2018 %I Institute of Advanced Engineering and Science %L SisLab2914
