beta = 200 V_BE (sigma_n) = 0.6 V What does the designer probably want from this circuit? Find R_C, R_E, R_1, and R_2 For I_CQ 1 mA and stable bias.

Solution

a) This type of biasing arrangement is commonly used in the design of bipolar transistor amplifier circuits and greatly reduces the effects of varying Beta, ( ) by holding the Base bias at a constant steady voltage. This type of biasing produces the greatest stability

The Common Emitter Amplifier circuit has a resistor in its Collector circuit. The current flowing through this resistor produces the voltage output of the amplifier. The value of this resistor is chosen so that at the amplifiers quiescent operating point, Q-point this output voltage lies half way along the transistors load line
