48.1.2. Design Sequence from Output Impedance

Try these first

1. 1.

   What is the significance of output impedance in circuits?

   Hint

   Think about how circuits interact with their loads.

2. 2.

   Define transconductance.

   Hint

   Focus on its role in current flow.

3. 3.

   What is the first step in circuit design concerning output impedance?

   • Calculate transconductance
   • Determine output impedance
   • Select load capacitance

   Hint

   Think about the initial parameters required.

4. 4.

   True or False: Reducing input capacitance can improve circuit frequency response.

   • True
   • False

   Hint

   Relate it to overall circuit performance.

5. 5.

   Design a circuit with a specified output impedance of 50 Ohms. Use the known parameters to calculate the transconductance and the required drain current.

   Hint

   Ensure you have all the values for calculations.

6. 6.

   Given a common collector configuration, calculate the expected collector current if the transconductance is 2 mS and the input voltage is 1 V.

   Hint

   Remember to check the unit conversion for current.
