Seonghan Ryu

Abstract

This paper presents a multiband low phase noise CMOS VCO with wide frequency tunability using switched bondwire inductor bank, for operation in the medical wireless frequency band. The combination of bondwire inductor and CMOS switch transistor enhances frequency tunability and improves phase noise characteristics. All most of the medical wireless frequency bands can be covered by the single VCO proposed in this paper. The proposed multiband VCOs, VCO1 operates from 2.3 GHz to 6.3 GHz with phase noise of -136 and -122 dBc/Hz at 1 MHz offset frequency, respectively, and VCO2 operates from 4.9 GHz to 12.7 GHz with phase noise of -122.3 and -111.8 dBc/Hz at 1 MHz offset frequency, respectively. Switched bondwire inductor bank shows high quality factor Q at each frequency band, which allows better tradeoff between phase noise and power consumption. The proposed VCO1 is designed in TSMC 0.18um CMOS process and consumes 7.2 mW power resulting in figure of merit(FOM) of -189.3 dBc/Hz at 1 MHz offset from 6 GHz carrier frequency, and the proposed VCO2 is designed in SEC 65nm CMOS process and consumes 8 mW power resulting in figure of merit(FOM) of -184.6 dBc/Hz at 1 MHz offset from 12 GHz carrier frequency.
