Muhammad's Paper to be Presented in the 2017 IEEE ISCAS
A Calibration-Free Low-Power Supply-Pushing Reduction Circuit (SPRC) for LC VCOs," in the 2017 IEEE International symposium on circuits and Systems (ISCAS), Baltimore, Maryland, May 2017.Congratulations to Muhammad Ahmed for the acceptance of his paper entitled "
This paper proposes a calibration-free low-power circuit to reduce the sensitivity of LC VCOs to power supply variations, i.e. supply-pushing. At the highest Kv value of 26 MHz/V, simulation results show 14.5-kHz and 1.01-MHz peak-to-peak deviation from a 1.9-GHz center frequency for a 50-mV supply variation with and without the proposed circuit, respectively. This is equivalent to a supply pushing of 290 kHz/V with the proposed circuit versus 20 MHz/V without it, which is about 70-times improvement in supply pushing over conventional VCO implementations.
