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…
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…
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…
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.…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer…
What is Surge Current? - Definition and Workings Before switching on of power supply, the filter capacitor is uncharged [Fig. 9.23]. At the instant the power supply is switched on,…
Transition and Diffusion Capacitance: Transition and Diffusion Capacitance - Electronic devices are inherently sensitive to very high frequencies. Most shunt capacitive effects that can be ignored at lower frequencies due…
Up Down Circuit Analysis: Any circuit has independent variables (such as source voltages and branch resistances) and dependent variables (such as voltage drop across resistors, current and power). Determination of…
