Parametric Sweep Simulation of a BJT
... Note: This is called a family of I-V curves for a BJT. The x-axis is still the “swept” variable (VCE) and the y-axis is still the collector current. However, now there is one I-V curve for each value of IB that we specified: 0µA, 10µA, 20µA, 30µA, 40µA, and 50µA. From the markers on the blue graph, ...
