Finding the parallel resistance across CL capacitors 01

Finding the parallel resistance across CL capacitors 01 PUBLIC

If CL applies the same sort of techniques as SPICE then CL probably places a very high value resistor in parallel with a capacitor as part of the model. This simulation presents three ways to find the...
