Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from ...

Many high-speed applications require driving a circuit element that is capacitive in nature. In order to gain bandwidth, capacitive loads are often driven by a buffer; however, most high-speed buffers ...

Some ideal op amp configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor non-idealities can affect various circuit parameters such as common mode rejection ...
