Abstract :
A self-biased phase-locked loop (PLL) uses a sampled feedforward filter network and a multistage inverse-linear programmable current mirror for constant loop dynamics that scale with reference frequency and are independent of multiplication factor, output frequency, process, voltage, and temperature. The PLL achieves a multiplication range of 1-4096 with less than 1.7% output jitter. Fabricated in 0.13-μm CMOS, the area is 0.182mm2 and the supply is 1.5 V.
