    Hello,

    I'm doing some abstract simulations with PSpice Student 9.1 from former OrCAD including a GAIN block (from the abm lib) and an E block (from the analog lib). I was expecting these blocks to have high impedance inputs, but I get current flow on the input pins even at the GAIN block in the order of the voltage on these pins. Does anybody know why or how I can get high impedance inputs (different model blocks or changing parameters etc.) respectively?
