    I recently read in a journal that the compander and the adaptive delta modulator circuit could be implemented through OTAs. it was mentioned that the value of step size and µ ( they were using a µ law compander circuit) could be varied by varying the transconductance of the otas used. how are these parameters varied in conventional compander and delta modulator ckts? I want to know the advantage of using otas for these ckts.

    I almost laughed out loud when I read this gobbledeegook but held my tongue, being well aware of my own ignorance. As you can see, you didn't get much feedback and I'd guess that's because few folks here had a remote clue what you were talking about!
