Try these first

1. 1.

   What is the primary advantage of using a cascode amplifier?

   Hint

   Think about what amplifiers need to handle signals better.

2. 2.

   What does output resistance influence in an amplifier?

   Hint

   Consider how signal strength is altered by impedance.

3. 3.

   What is the main purpose of a cascode amplifier?

   • To reduce gain
   • To increase bandwidth
   • To increase gain while improving bandwidth
   • To minimize output resistance

   Hint

   Think about why you would use more than one transistor in an amplifier.

4. 4.

   True or False: Increasing the output resistance always improves the bandwidth of an amplifier.

   • True
   • False

   Hint

   Review how output characteristics interact with frequency response.

5. 5.

   Design a cascode amplifier that effectively balances gain and bandwidth under given constraints. Identify the resistance values and operational conditions needed.

   Hint

   Start with known formulas for gain and bandwidth and plug in values.

6. 6.

   Evaluate how modifying different parameters in a cascode amplifier, such as transistor types or currents, might optimally adjust output resistance and gain.

   Hint

   Utilize lab experiments to see firsthand the effects of varying each parameter.
