Question 2.
Define the cutoff frequency.
Show hintHide hint
Consider the frequency limits of amplifier performance.
3Question 3.
What does the Miller effect enhance in amplifier circuits?
- Input Capacitance
- Output Resistance
- Input Resistance
Show hintHide hint
Think about feedback and how it affects capacitance.
4Question 4.
True or False: The lower cutoff frequency can be calculated using the product of resistance and capacitance.
- True
- False
Show hintHide hint
Recall the cutoff frequency formulas.
Question 5.
A common emitter amp shows a mid-gain of -10, can we find the lower cutoff frequency if the input resistance is 10k and capacitance is 10nF?
Show hintHide hint
Remember to substitute values correctly into the formula.
Question 6.
Given a common source amplifier, if Vth is 0.5 V and Vgs is 2V, what’s the effective transconductance if the Id is estimates at 1.5 mA?
