Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...
A while back, I mentioned 1 that we needed a clean test fixture to measure an operational amplifier's input current in the low femtoampere region. But aside from a neat little integrating capacitor ...
How to effectively measure ultra-low bias current by recreating the measurement scheme from an app note. Measuring input capacitance and input current. Creating a better measurement environment. 3. Cp ...
