Abstract:
This article introduces a CP-sampling (CS)-fusion PLL architecture that combines the advantages of PFD-CP PLLs (robust and speedy locking) and sampling PLLs (low jitter/power) in a single loop. The PFD sends pulsewidth-modulation (PWM) pulses to a merged $mathbf {G_{m}}$ /CP (GCP) block so that the phase error …
