This paper presented a 158-204 GHz frequency multiplier with 3 rd and 4 th harmonic suppression in 90-nm CMOS technology. A push-push doubler topology is implemented in this circuit. The W-band differential signal is made by Marchand balun. In order to achieve the goal of 4th harmonic suppression, a...
