An operational amplifier has a well balanced difference input and a very high gain.
It is similar to the operational amplifier, but also has differential output pins.
It should be expected that the outputs of even the simplest operational amplifiers will have at least two poles.
An example of a macromodel is the Boyle circuit for the 741 operational amplifier.
Alternatively, another operational amplifier can be chosen that has more appropriate internal compensation.
For example, the 741 might be considered a jelly bean operational amplifier.
Differentiators based on operational amplifiers do not suffer from drift.
An operational amplifier measures the difference, and generates an error signal.
The following analysis is based on the assumption that the operational amplifier is ideal.
Along with slew rate, this is one of the reasons why operational amplifiers have limited bandwidth.
