Hence people use more current, but also more degeneration, so you get the same gain but with better driving ability for capacitance and so better slew rate. F. Webtechniques dynamically increase the slew-rate, thus keeping low the quiescent current without using class AB solutions, [2-4]. This paper uses an auxiliary stage to enhance the slew-rate similarly to other published schemes (Section II), but it obtains higher effectiveness and also boosts the gain and the bandwidth of the op-amp.
