You gotta spill the beans on which modern mic preamp ICs use this technology.JohnRoberts said:Open loop gain that tracks with closed loop gain is a well explored characteristic of the "cohen" topology (also used inside modern mic preamp ICs).
Yes, the Transamp I think was the first 'op amp' to employ this technique but I was not aware it was now embedded in ICs.I mentioned this in passing in my 1980 console performance article (when describing Transamp used in a summing amp).
