This paper presents a dual voltage controlled oscillator (VCO) based integer-N phase locked loop (PLL) for navigation receiver operating at L 5-band and S-band. The PLL incorporates a multiplexer based extended range multi modulus divider (MMD) in the feedback path to cater to both L 5 and S band. Fabricated in UMC 65-nm CMOS, the PLL consumes 7.9 mW power from 1.0 V supply. The PLL achieves a phase-noise (PN) of-121 dBc/Hz and-120 dBc/Hz at 1 MHz offset for L 5 band and S-band, respectively achieving a best figure-of-merit (FoM) of 179.9 dBc/Hz. © 2022 IEEE.
