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 function can be expressed in terms of node voltage variables. Therefore, dependent current sources will affect the coefficients of node equation, ...
