A self-biased phase-locked loop (PLL) uses a sampled feedforward filter network and a multistage inverse-linear pro-grammable
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- m CMOS, the area is 0.182 mm and the supply is 1.5 V.
