Abstract :
A 60 GHz phase-locked loop (PLL) synthesizer with an injection locked frequency divider (ILFD) is presented. The PLL employs a simple and fast calibration algorithm consisting of the VCO sub-band selection and the adjustment of the ILFD locking range. The proposed PLL is demonstrated using 90 nm CMOS. The calibration process converges within 100 μsec at all 4-channels defined by the Wireless Gigabit Alliance (WiGig).
