where gm 1is the gain boosting amplifier input stage transconductance,i.e.the technique relies on accurate matching of the two capacitors and a fixed gm 1ÂR 2product to be effective.Complete analysis of Fig.3with the output stage reveals that the above choice,which sets the additional ...
many options are available to us. We can use a pentode input stage, with the same cathode-to-B+ resistor in place (or even a high-mu triode). Or we can use two triodes in a cascode topology (with
