DC Sweep Test

 

This analysis is often used to generate the input/output characteristics of circuits. In its most common form, the input can be a constant current source or a constant voltage source. However, we have added a new feature in B2 Spice. The input now can also be a temperature or a device parameter or a model parameter. The input is swept through a set of values, and for each value the DC operating point of the circuit is calculated. That is, all capacitors are opened, all inductors shorted, and voltage and current sources (except for the input) are set to their initial values.
