48.1.2. Voltage Gain Calculation

Try these first

1. 1.

   What does voltage gain (A_v) represent in an amplifier?

   Hint

   Think of it as how much the amplifier enhances the signal.

2. 2.

   Define the term 'operating point'.

   Hint

   It's important for understanding amplifier function.

3. 3.

   What is the voltage gain in an ideal common collector amplifier?

   • 0.1
   • 1
   • 10

   Hint

   Consider basic principles of amplification.

4. 4.

   True or False: The operating point determines how a transistor amplifier performs.

   • True
   • False

   Hint

   Think about where the transistor needs to be for accurate amplification.

5. 5.

   You designed a common collector amplifier with a Vdd of 10V, R_E of 1kΩ, and a target I_C of 2mA. Determine the required base-emitter voltage for proper operation.

   Hint

   Convert I_C to I_E using the available transistor parameters.

6. 6.

   In a common drain amplifier, if g_m is found to be 1mA/V and r_o equals 50kΩ while R is 10kΩ, find A_v.

   Hint

   Remember to consider the appropriate r_i value for your context.
