A 60GHz class F-E power VCO with vector-modulator feedback in 65nm CMOS technology
2012
A structure of a millimeter-wave transmitter architecture based on a Power VCO principle including a vector-modulator as a feedback loop solution is presented. This structure is dedicated to the V-band around 60 GHz. The Power VCO is designed in 65nm CMOS technology of STMicroelectronics. It is composed of a 2 stages class F-E power amplifier inserted in a loop to fulfill the oscillation conditions. The simulation results shows 9.7dBm output power at 60 GHz, a phase noise of -91.6dBc/Hz at 1MHz offset, for a consumption of 157mW.
