70.6.1. Transformation Between Differential and Single Ended Representation

Try these first

1. 1.

   What is a single-ended amplifier?

   Hint

   Think about how many inputs/outputs it has.

2. 2.

   Define the term 'common mode signal.'

   Hint

   It is the non-differential part of the signals.

3. 3.

   What does a differential amplifier output?

   • Single input signal
   • Common mode signal
   • Difference between two input signals
   • Average of two signals

   Hint

   Focus on what the term 'differential' refers to.

4. 4.

   True or False: A single-ended amplifier has two inputs.

   • True
   • False

   Hint

   Think about the definition of single-ended.

5. 5.

   Given two input signals of 5V and 3V to a differential amplifier, calculate the output if the gain is 10.

   Hint

   Focus on the gain relationship with differential signals.

6. 6.

   Outline how you would convert a single-ended signal of 10V into a differential form.

   Hint

   Consider looking for equal contributions from each side of your differential representation.
