What is meant current dependent current source?
A dependent source is a current or voltage source whose value is not fixed (i.e., independent) but rather which depends on some other circuit current or voltage. The general form for the value of a dependent source is Y=kX where X and Y are currents and/or voltages and k is the proportionality factor.
What is a dependent current?
A dependent current source establishes a current, which is independent of the voltage across it, that is determined by the voltage or current at some other location in the electrical system.
How does LTSpice measure current?
To measure voltage across a component, click on the positive node to be measured, drag the mouse to the negative node and release the mouse. Measure current – To measure the current through a component, move the mouse cursor over the component and click.
What are the different dependent sources?
There are four possible dependent sources: the voltage-controlled voltage source (VCVS), the current-controlled voltage source (CCVS), the voltage-controlled current source (VCCS), and the current-controlled current source (CCCS).
What is the difference between independent and dependent current source?
Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.
What are examples of current sources?
Simple transistor current sources
- Constant current diode.
- Zener diode current source.
- LED current source.
- Transistor current source with diode compensation.
- Current mirror with emitter degeneration.
- Constant current source with thermal compensation.
What is an independent current source?
Independent Current Sources. An independent current source is an energy source that pushes a constant flow of electrons through an electrical circuit regardless of the load presented to it.
What is a current controlled current source?
A current controlled is a source which is controlled or driven by a current source. A voltage contolled is one which is driven by a voltage source. Now, Bjt is a current controlled because. Bjt has a finite input impedance so it has a small finite base current which controls the output current.
What is a dependent source?
In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. Dependent sources are useful, for example, in modelling the behavior of amplifiers. A bipolar junction transistor can be modelled as a dependent current…
