Question 1.
What is the primary function of a current mirror?
Show hintHide hint
Remember, it stabilizes currents in circuits.
Question 2.
How do you define a differential amplifier?
Show hintHide hint
Think about its inputs and outputs.
3Question 3.
What does a current mirror do?
- Reduces voltage
- Mirrors current
- Amplifies frequency
Show hintHide hint
Remember its role in current stabilization.
4Question 4.
True or False: A common mode gain should be high for good signal integrity in differential amplifiers.
- True
- False
Show hintHide hint
Consider the impact of unwanted signals.
Question 5.
You have a differential amplifier circuit with a current mirror where the transistors are biased to 2mA. If one branch experiences an increase to 2.1mA due to temperature effects, determine how this affects the mirrored current and the overall performance of the amplifier.
Show hintHide hint
Think about adjustments in response mechanisms.
Question 6.
Given a differential circuit with varied resistor values, calculate the new common mode gain if the resistors change to 100kΩ each and verify its effect on signal rejection.
Show hintHide hint
Check formulas concerning common mode gain adjustments.
