I am trying to model an oscilloscope probe(active probe).
The voltage source in the circuit is from the device under measurement.
Let's say a 100MHz clock.
The probe signal and ground lead inductance are represented by 2 inductors, then a small series resistor. I made up the value of the series resistor.
The input capacitance is 1pF and resistance is 1M.
How do I calculate the voltage spike (overshoot) caused because of the inductance?
Another question - when the signal rises from 0 to 5v, the inductor L1 opposes the change. When the current reaches L2, does L2 also oppose the change?
