Abstract :
In this paper, a 64.3-66.2 GHz digitally calibrated phase-locked loop (PLL) is presented in 0.13 mum CMOS technology. A digital calibration circuit is adopted to align the center operation frequency between the VCO and the divider. At 64.3 GHz, the measured phase noise at 1 MHz offset is 84.1 dBc/Hz. The PLL consumes 72 mW without output buffers from 1.2 V supply.
