Methods

Initialize(out double, out double, out double, out bool)

Initializes the voltages that need to be used for calculating the current iteration.

Declaration
protected void Initialize(out double vgs, out double vds, out double vbs, out bool check)
Parameters
Type Name Description
double vgs

The gate-source voltage.
double vds

The drain-source voltage.
double vbs

The bulk-source voltage.
bool check

If set to true, the voltages have been limited to help convergence. If this is the case, then a new iteration should be calculated.

Events

UpdateContributions
