Input Characteristics

In case of common emitter p-n-p transistor input characteristic is a graph drawn.

Draw a circuit diagram of a transistor amplifier in CE configuration. Define the terms (i) Input resistance and (ii) Current amplification factor. How are these determined using input and output characteristics?

Consider the circuit arrangnent shown in Fig. for studying input and output characteristics of npn transistor in CE configuration. Select the values of R_ and R_ for a transistor whose V_(BE)=0.7V , so that the transistor is operating at point Q as shown in the characteristics shown in Fig. Given that the input impedance of the transistor is very small and V_(C C)=V_(BB)=16V , also find the voltage gain and power gain of circuit making appropriate assumptions.

The ratio (R) of output resistance r_0 and the input resistance r, in measurements of input and output charactersitics of a transistor is typically in the range :
