Measure the Input Capacitance of an Op AmpAkshay Bhat
where f1(-3dB) is the corner frequency as measured on the network analyzer with no op amp installed, and RTH1is the Thévenin-equivalent series resistance. RTH1is a function of the inserted series resistor, the input termination resistance (50Ω), and the source impedance at the power spli...

David L. Terrell, in Op Amps (Second Edition), 1996 Input Impedance. The input impedance of the amplifier shown in Figure 2.3 is that resistance (or impedance) as seen by the source (vI). You will recall that the voltage between the (+) and (−) terminals of the op amp (vD) wil...
FIXES FOR OUTPUT PHASE–REVERSAL In many cases, the addition of an appropriate RLIMIT resistor will prevent output phase-reversal. However, many op amp manufacturer might not always give the RLIMIT resistance value appropriate to prevent output phase-reversal. But, the value can be determined ...
4.1.3Input resistance Theinput resistanceof an amplifier determines the load that the amplifier places on the source of the signal being fed into it. In electrical terms, a transducer can be represented as a voltage source in series with a resistance – the transduceroutput resistance –which li...

Conclusion The addition of input, output, or load capacitance to an op amp circuit decreases stability, which leads to overshoot in the time domain. The stability decrease is worse for a buffer than for other amplifier configurations. Reducing the resistance value that makes up the RC circuit ...
