Hi, I'm studying ΣΔ modulator. As we know, for the 1st order 1-bit ΣΔ ADC, there is a 1-bit quantizer which is realized by an analog comparator circuit.
But how to realize a 1-bit quantizer for ΣΔ DAC? I have looked for a lot of literatures but none of them mentioned it. I think it must be a very simple circuit but I just can't figure it out.
Anybody can give me a hint? Thank you very much!
