This letter presents an ultra-compact two-stage 60-GHz differential bi-directional amplifier (DBA) design in a 65-nm CMOS process. To satisfy the stability and gain requirements, a differential neutralized bi-directional common-source gain cell combined with the cross-coupled gm-boosting technique i...
