Abstract
Systems and methods disclosed herein provide for a fractional feedback divider with reduced jitter at the output without increasing the input clock frequency and with minimal power increase. Embodiments of the system provide for interpolating, with a multiplexer, different output clock signals depending on whether an extra half period of resolution from the input clock is needed for a certain output clock cycle.
