Question 1.
What is input impedance?
Show hintHide hint
Think about how much signal the circuit can accept without loss.
Question 2.
Explain the significance of voltage swing in amplifier design.
Show hintHide hint
Consider the maximum and minimum output voltages.
3Question 3.
What dictates the input impedance of an amplifier?
- Supply Voltage
- Resistor Values
- Gain Factor
Show hintHide hint
Look at how resistors interact within the circuit.
4Question 4.
True or False: Lower input impedance allows better signal preservation.
- True
- False
Show hintHide hint
Think about how impedance affects current draw.
Question 5.
Design a common gate amplifier with a specified input impedance of 300Ω and output swing of ±3V using a supply of 9V. Discuss the challenges faced in achieving this.
Show hintHide hint
Consider how resistors affect the overall circuit beyond just the values.
Question 6.
Given a scenario where the output swing is insufficient, propose modifications to the existing circuit components to meet specification without altering the topology.
Show hintHide hint
Think about what changes would offset the limitations encountered.
