Abstract
Described herein is a distributed analog loop filter that can be employed in a phase locked loop or a delay locked loop. A circuit block of the distributed analog loop filter includes at least two parallel equivalent circuit elements. The parallel equivalent circuit elements each have an input line. The input lines for each of the parallel equivalent circuit elements are activated sequentially, one after the other. The parallel equivalent circuit elements have sequentially produced outputs that are also activated sequentially, one after another. The parallel equivalent circuit elements extend the tuning range of distributed analog filter while reducing noise associated with the distributed analog filter.
