Abstract:
A continuous time sigma-delta analog-to-digital converter comprising: a summator of an input analog signal and a feedback signal; a feed-forward integrator path connected to the summator and configured to provide a digital signal; a feedback digital-to-analog converter to convert the digital signal into a feedback analog signal; a feedback low pass filter structured to filter the feedback analog signal and provide the feedback signal to the summator.
