6 sample questions

Question 1.
What is the concept of linearization in electronics?
Show hintHide hint
Think about behavior near a certain point.
Question 2.
What does the term gm stand for?
Show hintHide hint
It's a measure of control in a transistor.
3Question 3.
What does small signal model represent?
- A static model of the circuit
- A model focusing on linear variations
- An entire circuit model including DC
Show hintHide hint
Think about signals that are not constant.
4Question 4.
Is transconductance a measure of a MOSFET's efficiency?
- True
- False
Show hintHide hint
What does gm express?
Question 5.
You have a MOSFET with ID = 1 mA and Vgs = 2V. Calculate gm if Vth is known to be 1V. Analyze if this improvement in gm can amplify a signal.
Show hintHide hint
Look for the role of Vth when calculating gm.
Question 6.
If a circuit containing a MOSFET has a derived small signal gain of -10 and the input voltage is 10mV, what is the output?
Show hintHide hint
Negative gain indicates an inversion; be careful with signs.
