The influence of the capacitor C1 can be clearly recognized from the plot of the node voltages V$1
and V$2.

2.7.2 Analysis of a Differential Amplifier
Transient Analysis
In this section, we want to examine a more complicated circuit to demonstrate the features and
capabilities of the DAE solver. Consider the differential amplifier circuit shown in Figure 7.2
consisting of four bipolar junction transistors. We shall compute the transient response V out t
to a rectangular voltage pulse applied at node 1.
