Transistor Load Line Analysis (DC and AC Load Line and Q Point): The concept of Transistor load line analysis is very important in understanding the working of a transistor. It is defined as the locus…
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 the input terminals and the…
Early Effect and Base Width Modulation: In active region, the emitter-base (EB) junction is forward biased and collector-base (CB) junction is reverse biased, so the barrier width at EB junction is negligible in comparison with…
Transistor Circuit Configurations (CB, CE, CC): As already mentioned, a Transistor Circuit Configurations is a three-terminal device (having three terminals namely emitter, base and collector) but we require four terminals—two for the input and two…
Ebers Moll Model for PNP Transistor: Device modelling aims at relating physical device parameters to device terminal characteristics. Device modelling is especially important for integrated circuits, since simple and accurate device models are required to…
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 thin region (or section) is…
Current Amplification Factor: There are two current amplification factors, the alpha factor (α) and the beta factor (β) defined below : The alpha factor (α) is also called the current amplification factor and is the…
Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into the emitter is referred to…
Important Points Regarding Working of Transistors: The noteworthy points regarding working of transistors are summarized below. 1. Current conduction in N-P-N transistor is by electrons and the conventional current flow will be in the opposite…
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. For a moment if the…
