Question 1.
What is the purpose of a current mirror in a transistor circuit?
Show hintHide hint
Think about current duplication.
Question 2.
How do you calculate the voltage output in a transistor circuit?
Show hintHide hint
Use the formula: Vout = Vsup - Vbe.
3Question 3.
What is the primary function of a current mirror?
- To amplify current variations
- To maintain constant current
- To reduce circuit complexity
Show hintHide hint
Focus on what current mirrors do.
4Question 4.
True or False: Quiescent current refers to the current flowing through the amplifier when no signal is applied.
- True
- False
Show hintHide hint
Consider when the circuit is active versus idle.
Question 5.
Design a differential amplifier with a current mirror load. Calculate the DC current through each transistor when the supply voltage is 12 V and the resistor is set to 10 kΩ.
Show hintHide hint
Readjust your calculations based on loading effects.
Question 6.
Given that the common mode gain is significantly lower than differential gain, discuss how this affects signal integrity in real-world applications.
Show hintHide hint
Think about how noise affects behavior in circuits.
