Frequency compensation

Because operational amplifiers are so ubiquitous and are designed to be used with feedback, the following discussion will be limited to frequency compensation of these devices. It should be expected that the outputs of even the simplest operational amplifiers will have at least two poles. A consequence of this is that at some c…
