Optimal dithering sequences for spurs suppression in Pulse Direct Digital Synthesizers

Spurs-free frequency synthesis with minimal noise floor is achieved by the classical Pulse Direct Digital Synthesizers using a new class of dithering sequences with specific statistical properties. The generation of dithering sequences having statistical properties very close to those of the ideal ones with low-complexity architectures is also discussed and used to form All-Digital frequency synthesizers of minimal footprint and power consumption.
