WebOp Amp Noise Theory and Applications Bruce Carter 10.1 Introduction The purpose of op amp circuitry is the manipulation of the input signal in some fashion. Unfortunately in the real world, the input signal has unwanted noise superimposed on it. Noise is not something most designers get excited about. In fact, they probably wish the WebResistors in the sensor circuit also affect the value of noise. Op amp noise can be classified into external or internal noise, depending on its source. Internal noise is generated in the op amp whereas external noise is caused by a feedback resistor and other external components.
