45.5. Effect of Collector Terminal Resistance

Try these first

1. 1.

   What is a common collector amplifier?

   Hint

   Think about where the output is taken from in this type of circuit.

2. 2.

   How does collector terminal resistance affect input resistance?

   Hint

   Consider the impact of resistances at different points in the circuit.

3. 3.

   What configuration is a common collector amplifier?

   • Output from Base
   • Output from Emitter
   • Output from Collector

   Hint

   Think about where the output is in relation to the input.

4. 4.

   True or False: Common collector amplifiers generally have a voltage gain close to 2.

   Hint

   Reflect on amplifier behaviors when calculating gain.

5. 5.

   Design a common collector amplifier circuit with specified input and output voltages, considering expected voltage gain and impacts of collector resistance.

   Hint

   Start with calculations for voltage gain and apply resistor values in your design.

6. 6.

   Analyze a common drain amplifier under practical conditions with specified collector resistance, outlining influences on output resistance and voltage gain.

   Hint

   Focus on understanding how practical resistance alters theoretical performance.
