In practice, a VCVS is often used in modeling operational amplifiers (op-amps), and can also be used in modeling a voltage signal chain more generally.Ī VCCS is a current source where the current is controlled by a voltage elsewhere in a circuit. In other circuits there will be an interconnection that makes the system harder to solve, but when there is no feedback, systems with controlled sources can be solved from input to output. From there, we can solve the right hand side directly: V Y = 5 Since no current flows into the controlling measurement terminals of VCVS1, then V1, R1, and R2 form a simple resistive voltage divider, with V A = 12īecause of the VCVS relationship, the source will look like a voltage of 10 V A B It is a specific case of the more general non-linear dependent source.

This example circuit is solvable by inspection because there is no feedback between the controlling side and the controlled side of the circuit.

For current controlled sources these act like a short-circuit current measurement in series with the controlling current.Ī VCVS is a voltage source where the voltage is controlled by a voltage elsewhere in a circuit. For voltage controlled sources these act like an open-circuit voltage measurement in parallel with the controlling voltage. Just as there are two kinds of independent sources (voltage and current), there are four basic types of dependent sources: their output can be either voltage or current, AND their input can be either voltage or current.Įach dependent source has two output terminals, just like an independent source would.Įach dependent source also has two input terminals, thought these are not always explicitly shown. Voltage and current are the two primary state variables in an electronic system. Many transistor situations can be modeled as though a small controlling current or voltage signal at one terminal can control a much larger current or voltage at another terminal. These dependent sources are important to understand because they’re how we model and analyze more complicated components, like transistors.
In particular, we’ll consider linear dependent sources, which have a value proportional to their controlling value, related only by some scaling constant. In this section, we’ll now consider dependent sources, which have a voltage or current value that is controlled by some voltage or current value elsewhere in the circuit. Our previous discussion of ideal voltage and current sources exclusively considered independent sources, which had a fixed specified voltage or current regardless of whatever else was going on in a circuit. Sources that are proportional to other currents or voltages in the circuit.
