based on the oversampling ratio (OSR), enhancing both power efficiency and signal quality[1]. Another study introduced a discrete-time delta-sigma modulator that employs a cascoded floating ...

The AR36T05 is a soft macro low-power high-performance digital microphone interface modulator IP. The IP converts stereo/mono 1-bit pulse-density modulated (PDM) bit stream data from external ...

It then uses Sigma-Delta modulation to encode the analog signal into a binary bitstream. You should really try this out. The picture above is from when I was testing it out since it only took a ...
