This paper presents a low phase noise (PN), dual voltage controlled oscillator (VCO), integer-N phase locked loop (PLL) for navigation receiver operating atL5andSbands. The PLL incorporates a proposed extended range multi modulus divider (MMD) in the feedback path. Fabricated in UMC 65nm CMOS, the PLL is powered at 1.2V supply consuming 12mW power. The PLL achieves a PN of −122 dBc/Hz and −120 dBc/Hz at 1M Hz offset forL5-band and S-band respectively.
