DC Sweep

Figure 56 Example schematic EXAMPLE.OPJ.
To calculate the DC response of an analog circuit, PSpice
removes time from the circuit. This is done by treating all
capacitors as open circuits, all inductors as shorts, and
using only the DC values of voltage and current sources.
In order to solve the circuit equations, PSpice uses an
iterative algorithm. For analog devices, the equations are
continuous.
