Methods

LimitFet(double, double, double)

Limiting function for a FET.

Declaration

public static double LimitFet(double newVoltage, double oldVoltage, double threshold)

Parameters

Type	Name	Description
double	newVoltage	New voltage.
double	oldVoltage	Old voltage.
double	threshold	Threshold value.

Returns

Type	Description
double	The new voltage, limited if necessary.

Remarks

Update taken from ngSpice, which was fixed by Alan Gillespie's code.

LimitVds(double, double)

Limiting function for the drain-source voltage.

Declaration

public static double LimitVds(double newVoltage, double oldVoltage)

Parameters

Type	Name	Description
double	newVoltage	The new voltage.
double	oldVoltage	The old voltage.

Returns

Type	Description
double	The new voltage, limited if necessary.

MeyerCharges(double, double, double, double, out double, out double, out double, double, double)

QMeyer method for calculating capacitances.

Declaration
