3Question 3.
What is the formula for calculating the lower cutoff frequency?
- A) fL = 1/(2π × R × C)
- B) fU = 1/(2π × R_par × C)
- C) Av = Vo/Vi
Show hintHide hint
Think about how frequency interacts with resistance and capacitance.
4Question 4.
True or False: The upper cutoff frequency is influenced by the input capacitance.
- True
- False
Show hintHide hint
Consider which components play roles at higher frequencies.
Question 5.
A common source amplifier has a lower cutoff frequency of 10 Hz and an upper cutoff frequency of 450 kHz. Given a load capacitance of 10 pF, what would happen to the upper cutoff frequency if this capacitance is increased to 100 pF?
Show hintHide hint
Consider how higher capacitance affects the circuit's impedance.
Question 6.
Discuss how design choices in component values impact the overall frequency response of an amplifier.
Show hintHide hint
Think about what happens when you change resistances and capacitances in the context of frequency.
