9.2.1. Introduction to I-V Characteristics

Try these first

1. 1.

   What is the typical behavior of I_C with respect to V_BE?

   Hint

   Think about how a diode behaves when forward-biased.

2. 2.

   Define the term β in the context of BJTs.

   Hint

   Consider how current amplification is important in circuits.

3. 3.

   What does β represent in a BJT?

   • Voltage Gain
   • Current Gain
   • Power Gain

   Hint

   Consider the concept of amplification in transistors.

4. 4.

   A PNP transistor operates by using which type of charge carriers?

   • True
   • False

   Hint

   Remember the carrier types for each transistor.

5. 5.

   Design a simple amplifier circuit with an NPN BJT. Calculate the values of resistors needed to achieve a target β of 200 if the base current is set at 10 µA.

   Hint

   Use the relationships established between I_B, I_C, and β.

6. 6.

   Compare the I-V characteristics of NPN and PNP transistors in a graphical representation showing both active and saturation regions.

   Hint

   Make sure to differentiate the character of each curve.
