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,…
Hybrid Parameters of Transistor or h Parameters and Hybrid Model: A box representing a two-port network is illustrated in Fig. 11.1. The terminal behavior of a two-port device may be…
Leakage Current in a Transistor and Breakdown Voltage: Leakage Currents: In CB circuits shown in Fig. 10.77, if emitter current is made zero, the B-C junction still remains reverse biased…
What is BJT Beta Rule? Like transfer of primary and secondary winding impedances of a transformer, resistance from one part of a transistor circuit can be referred to another parts.…
Transistor approximation (Ideal, Second and Higher): An NPN transistor is shown in Fig. 10.71 (a). Voltage appearing across the emitter diode is denoted by VBE and that appearing across the…
What is Thermal Runaway and Heat Sink? The maximum average power PC max which a transistor can dissipate depends upon the construction of the transistor and may lie in the…
How to use a Transistor as a Diode - Working and Equation: The transistor can be modified to operate as a diode by short circuiting the two transistor terminals, as…
