A constant loop bandwidth fractional-N frequency synthesizer for GNSS receivers
A constant loop bandwidth fractional-N frequency synthesizer for portable civilian global navigation satellite system (GNSS) receivers implemented in a 130 nm 1P6M CMOS process is introduced.Via discrete working regions,the LC-VCO obtains a wide tuning range with a simple structure and small VCO gain.Spur suppression technology is proposed to minimize the phase offset introduced by PFD and charge pumps.The optimized bandwidth is maintained by an auto l…查看全部>>
