Question 1.
What is the primary function of a current mirror?
Show hintHide hint
Think of it as a 'copy' device within circuits.
Question 2.
Define differential gain.
Show hintHide hint
It relates to how inputs influence outputs.
3Question 3.
What does a current mirror do?
- A voltage regulator
- Copies current from one transistor to another
- Increases voltage in a circuit
Show hintHide hint
Think about using 'reflection' in electricity.
4Question 4.
True or False: Common mode gain should be higher than differential gain for effective amplifier operations.
- True
- False
Show hintHide hint
Recall how noise can affect signal integrity.
Question 5.
Design a current mirror circuit with a specific collector current of 2 mA and analyze its gain performance in a differential amplifier setup.
Show hintHide hint
Use resistor values proportionate to the desired current output.
Question 6.
Given a circuit with varied resistor values affecting common and differential gains, derive a complete output voltage equation.
Show hintHide hint
Consider how each resistor modifies the overall impedance seen in the circuits.
