Abstract
An integrated analog to digital and sample rate converter includes sampling circuitry for receiving an analog signal and generating a single or multibit stream of digital signals at a first rate. A leaky integrator filter removes quantization noise from the stream of samples such that resampling can be carried out. Circuitry resamples the filtered stream of samples output from leaky integrator filter to generate an output stream of samples at a second rate.
