2.37-dBm-output 288–310 GHz frequency multiplier in 40 nm CMOS

We introduce a 288–310 GHz frequency multiplier fabricated with 40 nm CMOS technology. With 410.3 mW power consumption, this frequency multiplier has a conversion gain of 4.52 dB including that of its driver amplifier. The proposed system for input power / phase control of the power combiner enhances the output power of the frequency multiplier to 2.37 dBm at 300 GHz.
