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 ...

MT-034: Current Feedback Op Amps - Analog Devices
www.analog.comMT-034 This voltage is then buffered, and is connected to the op amp output. If RO is assumed to be zero, it is easy to derive the expression for the closed-loop gain, VOUT/VIN, in terms of the R1-R2 feedback network and the open-loop transimpedance gain, T(s). The equation can also be derived
