For the voltage source above, since the voltage depends on another
voltage, it is known as a voltage-controlled voltage source (VCVS).
Similarly, the current would be called a current-controlled current source
EE 442 dependent sources – 2 It is not necessary that the voltage source be dependent on another voltage
or that the current source depend on another current.
Current-controlled voltage source
– Vd = ci1 voltage-controlled current source
(VCCS) Id = dv1 Again, the controlling current, i1 and the controlling voltage v1 must be
deﬁned somewhere else in the circuit.
In these cases, the dependency factors will have units. For c, the units are
Ω. This does not mean that c represents some type of resistor – it is simply
the factor that relates the voltage to its controlling current. The units for d
must be siemans (S = Ω–1). EE 442 dependent sources – 3 Once the dependent source are located in circuit, along with the
deﬁnitions for the controlling currents or voltages, then cir...
