We present a 31–45.5 GHz injection-locked frequency divider (ILFD) implemented in a standard 90-nm CMOS process. To reduce parasitic capacitance and increase the operating frequency, an NMOS-only cross-coupled pair is adopted to provide negative resistance. Acting as an adjustable resistor, an NMOS transistor with a tunable gate bias voltage is connected to(More)
A Ka-band sub-harmonically pumped resistive mixer (SHPRM) was designed and fabricated using the standard 0.18-μm complementary metal-oxide-semiconductor (CMOS) technology. An area-effective asymmetric broadside coupled spiral Marchand balance-to-unbalance (balun) with magnitude and phase imbalance compensation is used in the mixer to transform local(More)
