P4. The BJT in the common-emitter amplifier in Figure 4 has ß = 100. The coupling capacitors may be taken as short circuits at the signal frequencies. Neglect the output resistance of the transistor. (a) Calculate the bias values of the collector voltage Ve, and the emitter voltage V, . (b)Draw the small-signal equivalent circuit of the amplifier, and find its overall voltage gain G, = (c)Find the maximum peak-to-peak input signal voltage before saturation or cutoff of the transistor occurs (i.e. find the peak-to-peak value of v, with symmetrical positive and negative variatiov at which the transistor enters cutoff or saturation, whichever occurs first. Consider the total collector voltage ve) ( Figure 4 +15 V S20 kn 15 kN 5 k. 500 kN 0.5 mÃ|
