4.5 NODAL ANALYSIS OF CIRCUITS CONTAINING DEPENDENT
CURRENT SOURCES
Dependent current sources do not pose a problem for nodal analysis. Independent current
sources appear on the right-hand side of node equations. However, dependent current sources
affect the coefficients of node voltage variables on the left-hand side of node equations.
The controlling variable of a linear dependent current source will be a voltage or a
current existing elsewhere in the circuit, but any voltage or current variable in the circuit can
be expressed in terms of node voltage variables. Hence, the dependent current source func-
tion can be expressed in terms of node voltage ...
