47.1.1. Lecture – 47

Try these first

1. 1.

   What is the primary function of a common collector amplifier?

   Hint

   Think about how it relates to impedance.

2. 2.

   What does the voltage gain of a common collector amplifier ideally approach?

   Hint

   Remember what it means to have minimal attenuation.

3. 3.

   What is the voltage gain of a common collector amplifier typically?

   • 0
   • 1
   • Infinity

   Hint

   Consider what it means for signal integrity.

4. 4.

   True or False: The common collector amplifier has low input impedance.

   • True
   • False

   Hint

   Think about how it matches impedance.

5. 5.

   Given a common collector amplifier with a collector current of 0.5 mA, determine its transconductance and comment on the implications for circuit design.

   Hint

   Remember to consider the thermal voltage at room temperature.

6. 6.

   Evaluate the impact on the upper cutoff frequency if the load capacitance is doubled. What will be the consequences for signal integrity?

   Hint

   Consider how capacitance affects the time constant in RC circuits.
