This work proposes a wide tuning oscillator mixer that operates from 56 to 64 GHz and is based on 90 nm CMOS technology. The circuit of a voltage control oscillator (VCO) comprises a mixer core and a coupled line marchand balun. The balanced mixer is symmetric, inherently broadband, and dependent on an LO balun that is combined with the parasitic capacitances from the mixer. The VCO is used in a 60...
An injection-locked push-push oscillator is developed for millimeter-wave signal source. A V-band push-push CMOS voltage controlled oscillator (VCO) is proposed in this study. A new core complementary Colpitts structure was adopted in a 90 nm CMOS process of FET induced capacitance of LC tank. The measured phase noise at 1 MHz offset is at 59 GHz. The power consumption of the VCO core is only 28.8...
