Question 1.
What does 'unloaded condition' mean in a transistor circuit?
Show hintHide hint
Think about how a garden hose works without a nozzle!
Question 2.
What does the common base configuration primarily serve as?
Show hintHide hint
Consider the input and output flow characteristics.
3Question 3.
What is the purpose of grounding the base in a common base configuration?
- To create an unloaded condition
- To increase input resistance
- To reduce output voltage
Show hintHide hint
Consider why we want to short certain components.
4Question 4.
True or False: Current gain in a common base configuration is typically less than 1.
- True
- False
Show hintHide hint
Recall the key points we discussed about the transistor characteristics.
Question 5.
If a transistor in a common base configuration has an input current of 40 μA and an output current of 39.5 μA, calculate the current gain and discuss why it is less than 1.
Show hintHide hint
Reflect on the physical limitations and resistances affecting current transmission.
Question 6.
Design a simple common gate configuration using a MOSFET and calculate the expected current gain if the input current is anticipated to be 50 μA.
Show hintHide hint
Consider the properties of MOSFETs and their lack of source resistance impact.
