Comparison between RTW VCO and LC QVC 12 GHz PLLs

Abstract

This paper reports comparisons between RTW VCO and LC QVCO 12 GHz PLLs, designed in a 130 nm CMOS technology. The phase noise at 1MHz offset from the carrier is -102 dBc/Hz for the RTW VCO PLL and -98 dBc/Hz for the LC QVCO PLL, and the power consumption is 39mW and 17 mW, respectively.
