65.2.2. Voltage Gain and Bandwidth Considerations

Try these first

1. 1.

   What is the main purpose of a cascode amplifier?

   Hint

   Think about signal strength improvements.

2. 2.

   Define bandwidth in electronic circuits.

   Hint

   Consider how signals vary in terms of frequency.

3. 3.

   What component increases voltage gain in a cascode amplifier?

   • Passive Load
   • Active Load
   • Signal Generator

   Hint

   Consider which type of load would boost performance.

4. 4.

   True or False: A higher voltage gain implies a wider bandwidth.

   • True
   • False

   Hint

   Think about the gain-bandwidth product.

5. 5.

   Design a cascode amplifier that maximizes voltage gain while retaining reasonable bandwidth. Specify your resistor values.

   Hint

   Refer to the relationships defined between resistance and gain!

6. 6.

   Given a desired gain of 4000, calculate the necessary equivalent resistance considering a transconductance of 2mA/V.

   Hint

   Use the formula to isolate resistance.
