Abstract :
This paper presents a 60-GHz sub-sampling PLL using a dual-step-mixing injection-locked frequency divider (ILFD). The sub-sampling operation achieves lower in-band phase noise, and the dual-step-mixing ILFD realizes a low power operation. The proposed synthesizer has been implemented in a standard 65-nm CMOS technology. It achieves a phase noise of − 115dBc/Hz at 10MHz offset. The sub-sampling operation helps reducing an integrated jitter from 12ps to 2.1ps. It consumes only 34mW.
