CMOS and JFET-input op amps are often selected for their low input bias current (I B). But there is more to the story than the single line in a spec table—subtleties that you should be aware of. The ...
The Junction Field Effect Transistors (JFET) has a channel consisting of N-type semiconductor or P-type semiconductor material and the gate is made of the opposite semiconductor type. The junction FET ...
