Show hintHide hint
Remember the roles of RD and gm in this equation.
Question 2.
State one reason why the input resistance of a Common Source Amplifier is idealized to be infinite.
Show hintHide hint
Think about the properties of MOSFET gate terminals.
3Question 3.
What is the formula for calculating voltage gain (A) in a Common Source Amplifier?
- A = RD * gm
- A = -RD * gm
- A = gm / RD
Show hintHide hint
Focus on the roles of RD and gm in amplification.
4Question 4.
True or False: The input resistance of a Common Source Amplifier is considered infinite.
- True
- False
Show hintHide hint
Think about the characteristics of the MOSFET structure.
Question 5.
Design a Common Source Amplifier with an RD of 10kΩ and gm of 5mA/V. Calculate the voltage gain.
Show hintHide hint
Use the standard voltage gain formula.
Question 6.
Given a MOSFET with a transconductance (gm) of 3mA/V and a parasitic capacitance of 15pF, determine the effect of the Miller capacitance.
Show hintHide hint
Remember the Miller effect influences input capacitance.
