Abstract :
Fully-digital single-bit-output (DAC-less) frequency synthesizers with imbedded modulation capability are considered as the foundation for building fully-digital RF transmitters. The paper presents an overview of recent results and introduces a new architecture based on sigma-delta like feedback noise shaping.
