Popis: | A modified fT-doubler with current-reused technique is proposed to realize a low power and low phase noise V-band voltage controlled oscillator (VCO) in a standard 1P9M 90-nm CMOS. The proposed technique not only increases the operation frequency but also reduces the DC power consumption at millimeter-wave frequencies. The short circuit unity gain frequency fT of the modified fT-doubler yields a 31% improvement compared to that of conventional one. Measurement result shows that the designed VCO achieves a phase noise of −115.4 dBc/Hz at 10-MHz offset under a low power consumption of 2 mW. The figure-of-merit is up to −187.7 dBc/Hz. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1752–1755, 2015 |
