nulling resistor
Hi all,
From paper/text, it usually needs a compensation cap and a nulling resistor(normally realized by transistor biased in linear region) in two-stage op amp. The usual placement is as follows:
output of first stage---cap---resistor---output of second stage
could we switch the cap and the resistor like the below?
output of first stage---resistor---cap---output of second stage
If not, please give me your reasons. Many Thanks.
