Measuring device for very short current impulses

摘要

The circuit has an integrator stage with a high-gain amplifier (A1) whose output is looped back to an input using a resistor of value Rp and a capacitor of value (Cint). A differentiator stage (DR) has a high-gain amplifier (A2), and an input capacitor of value (C2) between an output of the integrator stage and an input of the amplifier (A2). A subtractor stage (SS) receives the output from the integrator stage and differentiator stage on inputs, where the stage (SS) supplies, on its output, difference between voltages on its inputs.
