Abstract
All-digital frequency synthesis based on single-bit, Nyquist-rate, quantization of sinewave with independent and identically distributed random amplitude dithering is proposed. The output spectrum of the quantizer is derived in closed form and is related to the distribution of the random dither. Conditions for spurs-free output are derived, and the output dynamic range is defined. MATLAB simulation examples illustrate the results of the proposed approach.
