59.2.2. Output Resistance

Try these first

1. 1.

   Define output resistance in your own words.

   Hint

   Think about the load connected to the output.

2. 2.

   What does voltage gain represent?

   Hint

   Consider how amplifiers increase signals.

3. 3.

   What is the primary factor that determines output resistance in a common source amplifier?

   • Capacitance
   • Drain Resistance
   • Transconductance

   Hint

   Identify the components that directly influence output parameters.

4. 4.

   True or False: Cascading amplifiers can improve bandwidth.

   • True
   • False

   Hint

   Consider the advantages of using multiple stages in amplification.

5. 5.

   Design a multi-stage amplifier using one common source and one common drain. Calculate the total gain and explain the significance of the output resistance in maintaining system stability.

   Hint

   Work through the individual gains then multiply for the total.

6. 6.

   Evaluate how changing the load resistance affects the output voltage and discuss the implications for amplifier design.

   Hint

   Think about the relationship between resistance, voltage, and current in Ohm's law.
