Samenvatting

This work presents a 24 GHz integrated Phase-Locked Loop in a 60 GHz sliding-IF transceiver for IEEE 802.15.3c standard with low phase noise. For low phase noise, a varactor and MOM cap combination method is applied in this 24 GHz PLL. The capacitor bank is optimized to decrease the noise folding from circuit noise to phase noise within this method. This analog PLL is fabricated in a 65 nm CMOS technology with a phase noise of −98.8 dBc/Hz@1MHz, and the reference spur is −62.4 dBc. The power consumption of the PLL is 45.6 mW, including the output buffer.
