- True
- False
Show hintHide hint
Consider the influence of steady-state conditions.
Question 5.
Given a common collector configuration with a supply voltage of 12V, calculate the emitter current if the emitter resistor is 1kΩ and the base current is found to be 20µA.
Show hintHide hint
Start from the known voltage drop.
Question 6.
If a common drain amplifier has an input capacitance of 1pF and an output impedance of 500Ω, what is its upper cutoff frequency?
Show hintHide hint
Remember the formula for cutoff frequency in RC circuits.
