52.3.1. Practical Bias Arrangement in Common Gate

Try these first

1. 1.

   What is the purpose of biasing in a transistor amplifier?

   Hint

   Think about the active state of the transistor.

2. 2.

   What is a Thevenin equivalent circuit?

   Hint

   Consider how we can reduce complexity in circuits.

3. 3.

   What method is used to simplify a complex circuit into a single voltage and resistance?

   • Voltage Division
   • Kirchhoff's Law
   • Thevenin Equivalent

   Hint

   Think about the way we analyze and break down electrical circuits.

4. 4.

   True or False: The value of current gain in a common gate amplifier is generally less than 1.

   • True
   • False

   Hint

   Recall how current behaves in transistor configurations.

5. 5.

   Design a bias circuit for a common gate amplifier using a 9V supply. Specify resistor values and explain your choices.

   Hint

   Remember the principles behind voltage dividers.

6. 6.

   Analyze the effect of increasing the source resistor's value on the current gain of the common gate amplifier. What conclusions can you draw?

   Hint

   Consider how source resistance interacts with biasing and gain.
