WebOct 16, 2024 · V_gs = 0V.....and as FvM correctly stated this is the DC operation point. --> use a high ohmic resistor across G and S to ensure 0V DC. But you want to test input capacitance: --> connect a high quality foil capacitor from your ESR measurement device to G of the mosfet. Webcgg = cgc + cgb. When performing mosfet capacitance measurements you should make sure that the above holds true for your measurements. The cgc measurement is often …
