6 FAQs about [What are the regulations for capacitor models ]

Can a capacitor model be charge conserving?

For a capacitor model to be charge conserving, it must be such that if the voltage is changed and then returned to its original value, the final charge must equal the initial charge, regardless of the path taken or the starting point. This is true for models described with single-valued charge functions because q(vi) = q(vf) if vi = vf.

What makes a good capacitor model?

There is a requirement for unusual precision. If one plate of an oxide capacitor is a diffused layer—or a poly layer with a high sheet resistance—the capacitance will decrease slightly as the potential across the plates is increased. A competent model will reflect this nonlinearity. The capacitor is used at the high-frequency end.

What is a capacitance model?

Capacitance is an incremental or small-signal quantity that is defined as C = dq/dv. Defining a capacitor model by giving capacitance as a function of voltage results in the model not conserving charge.

Why does a capacitance model not conserve charge?

The reason capacitance-based models do not conserve charge is that capacitance is an incremental quantity that only accurately predicts the change in charge versus voltage for in- finitesimally small changes in voltage. The other method of defining a capacitor model, that of giving charge as a function of voltage, does conserve charge.

What happens when a capacitor is included in a circuit?

When a capacitor is included in a circuit, the current will change with time, as the capacitor charges or discharges. The circuit shown in Figure 20.5.1 shows an ideal battery 1 ( ΔV ), in series with a resistor ( R ), a capacitor ( C, two vertical bars) and a switch ( S) that is open.

Why are MOSFET capacitor models not fixed?

With a capacitance-based model, the small errors made on each step of the voltage trajectory accumulate and the final charge does not equal the starting charge. This example also partially illustrates why the MOSFET capacitor models in have not been fixed. It is first necessary to derive a charge equation that fits the model.
