48.1.4. Summary of Design Guidelines

Try these first

1. 1.

   What is output impedance?

   Hint

   Think about the impedance at the end of the circuit.

2. 2.

   Define transconductance.

   Hint

   It's about how voltage affects current.

3. 3.

   What is the primary starting point for designing these circuits?

   • Input Resistance
   • Output Resistance
   • Load Capacitance

   Hint

   Think of where impedance plays a critical role.

4. 4.

   Transconductance is?

   • True
   • False

   Hint

   Recall its definition.

5. 5.

   Design a common drain amplifier with a target upper cutoff frequency of 1 kHz and an associated load capacitance. What are the output impedance and resistive values you would calculate?

   Hint

   Use the relationship between frequency, capacitance, and resistance.

6. 6.

   A common collector circuit is required to have a specific voltage gain. If the load capacitance is known, how would you approach finding the necessary transconductance?

   Hint

   Check how gain relates to resistance and transconductance.
