A digital PLL with two-step closed-locking for multi-mode/multi-band SAW-less transmitter

This paper presents a digital phase locked loop (DPLL) with two-step closed-locking technique. The two-step locking allows us to use a simple phase detector, which achieves wide phase detect range and has no complex circuits for glitch compensation. The DPLL has three digital controlled oscillators...
