In order to enhance the maximum stable gain in D-band, the gain-boosting technique is adopted at the third, fourth, and fifth stage, enabling high gain performance over a wideband. According to the measurement results, the proposed work demonstrates competitive performances with 16.3-dB peak gain and 9.6-12.1-dB noise figure across the 3-dB bandwidth from 129 to 157.5 GHz.28-nm CMOS technology | D-band amplifier | gain-boosting techniqueconference paper10.23919/EuMIC58042.2023.102889992-s2.0-85177177767https://api.elsevier.com/content/abstract/scopus_id/85177177767
