48.1.1. Common Collector or Common Drain Circuit Analysis

Try these first

1. 1.

   What does the output impedance represent in a circuit?

   Hint

   Think about power delivery in a circuit.

2. 2.

   What is transconductance?

   Hint

   Remember the relation between input and output changes.

3. 3.

   What is the voltage gain of a common collector circuit?

   • 0
   • 1
   • 2
   • 3

   Hint

   Consider how amplifiers operate with respect to input and output.

4. 4.

   The output impedance of a common drain circuit is usually high.

   • True
   • False

   Hint

   Think about impedance definitions in transistor circuits.

5. 5.

   Imagine designing a common drain circuit with a load capacitance of 0.5uF and a power supply of 5V. Calculate the required output voltage gain if your aim is to maintain a cutoff frequency of 20kHz.

   Hint

   Think about how capacitance and frequency relate to resistance.

6. 6.

   You're tasked with adjusting a common collector circuit to achieve a higher output current without changing its voltage gain. What adjustments should you consider and why?

   Hint

   Focus on the relationship between voltage, current, and gain in transistor operations.
