Abstract: ABSTRACT This article presents a wideband phase-locked loop (PLL) front-end, which consists of a dual-core voltage-controlled oscillator (VCO) and a divide-by-four (D4) frequency divider in 90-nm CMOS technology. The switched inductors and varactor banks are used to enhance the tuning range of VCO. The D4 frequency divider is a body-biased injection-locked frequency divider (ILFD) cascoded with source-injection current mode logic (SICML) for wider locking range and lower power consumption. This PLL front-end demonstrates a 30.2% frequency tuning range (FTR) from 23.6 to 32 GHz and a phase noise of −101.22 dBc/Hz at 5.86 GHz with 1 MHz offset frequency. The output power is higher than −15 dBm among the operating bandwidth. The dc power consumption is 40.8 mW at 1.2 V and 1.5 V supply voltages. © 2017 Wiley Periodicals, Inc.
