Self-biased high-bandwidth low-jitter 1-to-4096 multiplier clock generator PLL

A self-biased PLL uses a sample feed-forward 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, and PVT. The PLL achieves a multiplication range of 1 to 4096 with less than 1.7% output jitter. Fabricated in 0.13/spl mu/m CMOS, the area is 0.182mm/sup 2/ and the supply is 1.5V.
