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 Webtransistor. In an integrated circuit op amp, this resistor often is from an ESD protection circuit in series with the base of the differential input stage (see Fig. 7.8). In some cases this noise dominates. Fig. 7.8: Thermal Noise Component Of Op Amp Noise For most integrated circuit processes, it is reasonable to assume ±20% tolerance for this

Since the signal generator can only go to +1V, I will amplify this noise signal with another op. amp. to reach those +14V. What I don't know is how to safely wire the circuit to superimpose my scope noise signal to the "production" op. amp. input (the op. amp. WebOp-amp voltage noise may be lower than 1 nV/√Hz for the best types. Voltage noise is the noise specification that is more usually emphasized, but, if impedance levels are high, current noise is often the limiting factor in system noise performance. That is analogous to offsets, where offset voltage often bears the blame for output offset, but ... Web• Burst noise • Avalanche noise In op amp circuits, burst noise and avalanche noise are normally not problems, or they can be eliminated if present.
