Concept of capacitor scaling

Abstract:

The present disclosure addresses a concept for capacitor scaling. A first capacitor is provided with a first signal capacitance between a first electrode and a second electrode of the first capacitor and with a first parasitic capacitance between the first capacitor's first electrode and AC ground. A sum of the first signal capacitance and the first parasitic capacitance yields a first total capacitance. A second capacitor is provided with a second signal capacitance between a first electrode and a second electrode of the second capacitor and with a second parasitic capacitance between the second capacitor's first electrode and AC ground. A sum of the second signal capacitance and the second parasitic capacitance yields a second total capacitance. While the first signal capacitance differs from the second signal capacitance, the first total capacitance equals the second total capacitance.
