48.2.2. Next Steps: Common Base and Common Gate Configuration

Try these first

1. 1.

   What is the main goal when starting to design a Common Drain circuit?

   Hint

   Think about what affects the circuit's interaction with the load.

2. 2.

   Define transconductance.

   Hint

   Think about the relationship between voltage and current in circuits.

3. 3.

   What is the first step in designing a Common Drain circuit?

   • Calculate transconductance
   • Determine output impedance
   • Find collector current

   Hint

   Consider what sets up all the following design parameters.

4. 4.

   True or False: Avoiding resistance in a circuit can lead to increased performance.

   • True
   • False

   Hint

   Think about the goal of simplifying circuit designs.

5. 5.

   Design a Common Collector amplifier with a specified gain and impedance. Outline your approach including calculations for each stage.

   Hint

   Start with the end requirements and work your way up, calculating each parameter step-by-step.

6. 6.

   Explain how you would adjust the circuit design if the load capacitance changes significantly. What parameters need to be re-evaluated?

   Hint

   Consider the impact of load on overall frequency response in circuit design.
