51.1.1. Introduction to Numerical Examples

Try these first

1. 1.

   Define voltage gain in the context of transistors.

   Hint

   Think about the amplifier's function: it boosts an input signal.

2. 2.

   What is input impedance?

   Hint

   Consider how it affects signal sources connected to the amplifier.

3. 3.

   What is the typical characteristic of a common base amplifier?

   • High input impedance
   • Low input impedance
   • No input impedance

   Hint

   Consider how they interact with their input signal sources.

4. 4.

   True or False: The voltage gain of a common base amplifier can be greater than 1.

   • True
   • False

   Hint

   Think about the role of amplifiers.

5. 5.

   Design a shock-sensitive common base amplifier with specifications on input range and output voltage; justify component selections.

   Hint

   Integrate the use of theoretical equations to support designs.

6. 6.

   Analyze the effects of increasing the collector resistor's value on voltage gain while keeping other parameters constant.

   Hint

   Graph performance parameters against resistor changes for better visualization.
