ET1310 – Analog Fundamentals

Exercise 2.1

1.) What is the most probable category of each transistor in the following figure?

3.) Find VE and IC in the following figure.

4.) For the base-biased pnp transistor in the following figure, assume ßDC = 200. Find IC and VCE

5.) A particular transistor is to be operated at a collector current of 50 mA. How high can VCE gowithout exceeding a PD(max) of 1.2 W?

6.) Assume the transistor in the following figure is a 2N3904. Can the power supply be increased to 24V without exceeding PD(max)?

7.) Assume that RC in the following figure was replaced with a 330Ω resistor.

a.) (a) What is the new value of IC and VCE?

b.) (b) What is the power dissipated in RC because of this change?

(c) What is the power dissipated in the transistor because of this change?
