A low-jitter and wide output frequency range ADPLL was proposed in this paper. The adopted PFD based on sense-amplifier flip-flop (SAFF) can effectively improve the jitter performance. The novel DCO with cascading structure consists of a coarse-tuning delay chain and a fine-tuning interpolator, obtaining both wide frequency tuning range and high resolution. A time-amplifier based sub-exponent TDC...
