A delta-sigma modulator has a first node at which is produced a difference signal equal to the difference in magnitude between a continuous time analog signal and an analog feedback signal generated from a digital output signal; an integrator, coupled to the first node, to integrate the difference signal, thereby producing a first integrated signal; a photonic sampler, coupled to the integrator, to sample the first integrated signal, thereby producing a sampled integrated signal; a quantizer, coupled to the sampler, to quantize the sampled integrated signal, thereby producing the digital output signal; wherein an output of the quantizer is coupled to the first node through a digital to analog converter. |
