Question 1.
What is common mode voltage?
Show hintHide hint
Think of it as the average voltage affecting both inputs.
Question 2.
State the significance of maintaining a proper DC operating point.
Show hintHide hint
What happens if the point shifts too high or too low?
3Question 3.
What is the common mode voltage?
- Single voltage at one output
- Average voltage at both inputs
- Voltage only at the negative input
Show hintHide hint
Remember the definition shared at the beginning.
4Question 4.
True or False: Maintaining the operating point too high will enhance amplifier performance.
- True
- False
Show hintHide hint
Think of the balance required between upper and lower limits.
Question 5.
Calculate the voltage drop across a resistor of 1kΩ if 0.2mA flows through it.
Show hintHide hint
Remember, Ohm's law is often the best approach for these calculations.
Question 6.
Determine the operating point if the supply voltage is 12V and the minimum common mode voltage is 0.6V.
Show hintHide hint
First calculate voltage drops with given values.
