Abstract
This paper describes a new first and second-order delta-sigma modulator (DSM) concept where the first integrator is extracted and implemented by a FM oscillator with the modulating signal as the input. The result is a simple DSM with no need for DACs, allowing straightforward multi-bit quantization. Without the FM oscillator, the modulator becomes a F/D converter with delta-sigma noise shaping
