Abstract: A compact, low power and global-mismatch-tolerant 0.8-6 GHz fractional-N PLL is designed to cover IEEE 802.11abg, PCS/DCS and cellular bands. Two new techniques are proposed to cancel the in ...

Abstract: This brief presents a compact and power-efficient full ring-oscillator (RO)-based cascaded fractional-N PLL. The proposed cascaded PLL consists of a RO-based DLL and type-II PLL as the first ...
