What is Focusing Device in Cathode Ray Oscilloscope and why it is required? Because of the mutual repulsion between the electrons, the convergent beam coming out from the accelerating anode…
Experimental Determination of Hybrid Parameters: Determination of hybrid parameters of a general linear circuit has already been discussed. For determination of hybrid parameters for a CE transistor, consider the circuits…
Transistor Hybrid Model: The basic assumption in arriving at a transistor linear model or equivalent circuit is that the variations about the operating or quiescent point are small and, therefore,…
Transistor Lead Identification and Testing: Transistor Lead Identification and Testing - After the transistor has been manufactured, as already discussed, leads of, typically, gold, aluminium, or nickel are then attached…
Transistor as an Amplifier - Circuit Diagram and Its Workings: The main utility of a transistor lies in its ability of amplifying weak signals. The weak signal is applied at…
Base Spreading Resistance: With two depletion layers penetrating the base, the base holes are confined to the thin region of P-type semiconductor illustrated in Fig. 10.12. The resistance of this…
What is Transistor Biasing? - Types of Biasing As already mentioned, for normal operation of a transistor emitter-base junction is always forward biased and collector-base junction is always reverse biased.…
Transistor Action : Operation of PNP Transistor: Transistor action - Transistors of both types (P-N-P and N-P-N) behave exactly in the same way except change in biasing and majority carriers.…
