Technical Examples
  1. A method of sampling an input signal in a delta-sigma modulator having at least an integrator stage and a feedback digital-to-analog converter (DAC) stage includes sampling an input signal at a sampling rate by alternately utilizing the two sampling capacitors during two sampling cycles such that the two sampling capacitors are each being utilized at half the rate of the sampling rate. Samples from the two sampling capacitors are summed at the sampling rate at an intermediate node with a feedback samples provided by the feedback DAC stage at the sampling rate to generate output samples which are output from integrator stage at the sampling rate.
