64.4.2. Voltage Measurements

Try these first

1. 1.

   Define voltage measurement in an electronic circuit.

   Hint

   Think about what voltage tells us in a circuit.

2. 2.

   What is a cascode amplifier?

   Hint

   Consider the structure and purpose of amplifiers.

3. 3.

   What is the primary advantage of a cascode amplifier?

   • Increases gain
   • Decreases gain
   • No effect on gain

   Hint

   Think about why amplifiers are used in circuits.

4. 4.

   True or False: Increasing resistance always improves bandwidth.

   • True
   • False

   Hint

   Consider the definitions of bandwidth and resistance.

5. 5.

   Design a cascode amplifier circuit with specified component values. Calculate the expected output voltage given an input current of 1.5mA and an input voltage of 0.5V.

   Hint

   Make sure you check all your resistance values and calculate gain first!

6. 6.

   Given a circuit with a 15 kΩ resistance and a supply voltage of 12V, calculate the expected voltage drop across the resistor with a current of 1 mA.

   Hint

   Don’t forget to stay consistent with your units!
