Electrical engineering: Feedback
Description
Feedback is the design technique where a part of the amplifier output "feeds back" to the input of the amplifier. The overall effect creates a very stable gain determined by resistor ratios.
Electrical engineering
Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside.
Operational amplifier
The operational amplifier, or "op-amp", is a common type of amplifier used everywhere in analog electronics. The op-amp has very high gain and differential inputs.
