MT-047: Op Amp Noise - Analog Devices
www.analog.comIn bias-compensated input stages and in current feedback op amps, the current noise cannot be calculated. The current noise in the two inputs of a current feedback op amp may be quite different. They may not even have the same 1/f corner. IN+ Figure 3: Input Current Noise . Current noise is only important when it flows in an impedance, and thus ...

www.analog.comtwo broadest classes of op amps, those using voltage feedback and current feedback. These two amplifier types are distinguished more by the nature of their internal circuit topologies than anything else. The voltage feedback op amp topology is the classic structure, having been used since the earliest vacuum tube based op amps of the 1940 and
