WebBasically, parasitic capacitance is a small distributed capacitance to ground. For traces on a normal board, the stray capacitance will be from a few pF to a few 10s of pF depending on the trace length and how close it is to the ground plane and other traces. There is nothing magic about this capacitance. Together with the signal's impedance ... WebAdding parasitic capacitance in parallel with the low resistor values (Rg) will produce undesirable results. When capacitance is in parallel to the Rf (feedback resistor), then one questions why the full bandwidth was not obtained. How then does the engineer or designer determine parasitic capacitance and its influence on the final board design?
