0) Opamps circuits always contain some sort of feedback mechanism, since to the open-loop gain of an opamp is infinite. That's not true. Think only about the many applications where the OPamp works like a comparator. Here, the "infinite" gain is even virtually increased, sometimes, by the use of positive feedback... Kai |
