ELECTRONIC CIRCUIT DESIGN


:

Question No. 1: Assume you are working in a laboratory at 27 centigrade with the circuit given in figure 1.
Analyse the circuit, determine the Q- point and answer the following questions:
a. Can we use it as an amplifier? Justify your answer based on your     analysis.

b. What will happen if you installed the circuit given in figure 1 in Jacobabad at the temperature
of 55 C. Still it is working or not? Is there any distortion in the output?
c. Do the temperature analysis i.e find the percentage change in ICQ and VCEQ. (5)
If the circuit in figure 1 is not working in Jacobabad, being electrical engineer suggest and
draw the circuit for working at 55 C temperatures effectively.

Assume β=125 @ 27 C and β=200 @ 55 C.
