Self-biasing greatly simplifies DLL and PLL designs. It
eliminates the need for precise currents, eliminates virtually
all process technology dependencies, and makes a wide operating
frequency range possible. The bandwidth to operating
frequency ratio and the PLL damping factor are fixed completely
by a ratio of capacitances. The operating frequency
range is limited only by the buffer stage design. Self-biasing
facilitates the construction of an input offset-cancelled charge
pump. Self-biasing also allows a PLL to have the largest
possible loop bandwidth over all operating frequencies for
minimal jitter accumulation. The phase-frequency comparator
design provides equal short duration output pulses for in-phase
inputs without reducing its maximum operating frequency.
