... EL4421, EL4422, EL4441, EL4442, EL4443, EL4444 Feedback Connections A feedback divider is used to increase circuit gain, and some precautions should be observed. The first is that parasitic capacitance at the -input will add phase lag to the feedback path and increase frequency response peaking or even cause oscillation. One solution is to choose feedback resistors whose parallel value is low ...
