The slew rate and bw of an ideal opamp are
WebJul 27, 2024 · Slew rate is defined as a large signal test because the input signal is supposed to have a fast edge that turn off one transistor in the input stage. When transistors turn on and off, linear approximations do not apply, so it is not small signal conditions.
