Constant Current Source in Differential Amplifier: An ideal current source provides a constant current regardless of the load connected to it. There are many applications in electronics for a circuit…
Difference between VSI (Voltage Source Inverter) and CSI (Current Source Inverter): The difference between VSI (Voltage Source Inverter) and CSI (Current Source Inverter) is given in below table Sl no…
What is Current Mirror? - Circuit Diagram and its Workings The two-transistor current source, also called a current mirror, is the basic building block in the design of integrated circuit…
Constant Current Bias in Differential Amplifier: In the differential amplifiers discussed so far, we have used the combination of RE and VEE to produce emitter dc bias current. Alternatively, constant…
Equivalent Circuit of Current Amplifier: The input signal in a current amplifier is essentially a current, and thus the signal source is most conveniently represented by its Norton equivalent (Fig.…
Common Drain JFET Amplifier or Source Follower: In the Common Drain JFET Amplifier circuit (also called the source follower), the output voltage is developed across source resistor RS. External load…
FET Biasing Methods - Fixed Bias, Self Bias, Potential Divider Bias and Current Source Bias: Unlike BJTs, thermal runaway does not occur with FETs. However, the wide differences in maximum…
What is Current Foldback? The current limiting technique maintains a constant load current at some specified value and under overload condition, the Vout drops to zero. But, in case of…
