Abstract
A digital frequency synthesizer can be implemented with single source design, a multiplexer design, a fractional divider design, or a frequency multiplier and frequency divider design. Implementations can utilize a controller dithering circuit or a delta-sigma modulator. The frequency synthesizer can be implemented in a CMOS structure and can utilize a clean up phase locked loop (PLL).
