Characteristics of Current Source
To discuss about various properties of current sources, we will enlist some characteristics of Current Sources
- Current Source supply a constant current in circuit to ensure a fixed current despite any variations in load or any change in voltage across source.
- They generally have infinite or very large resistances. This is to ensure that output current remains same even in case when load resistance varies. Having infinite impedance is just a concept since it is not possible so we try to achieve maximum impedance.
- Good current sources are insensitive to variation in load resistances. No matter load resistance increases or decreases, current source should ensure constant current supply.
- Current Sources are adjustable and stable devices since they can withstand variations in temperature, pressure i.e. they can operate in a range of environment conditions.
- Current Source show linearity. This is to ensure that the output generated is directly proportional to the input values.
Current Source
A current source is an integral part of electronic circuits which is used for supplying current in the circuit. In this article, we will discuss these current sources along with their types. We will also learn about their nature through some characteristics. These characteristics when put to use can be applied at various places which have been discussed through the applications. We will conclude the article with some points and list some frequently asked questions for reference.
