Chapter 1
- Amplifier Models
- These are purely models, and cannot be replicated in a real world environment. They are meant to explain.
- Trans stands for transfer - from voltage to current or visa versa.
- The inputs and outputs can be either current or voltage. This leads to 4 amplifier models.
- Voltage
- Current
- "As before, the input resistance accounts for the current that the amplifier draws from the signal source. The output resistance is now in parallel with the controlled source and accounts for the fact that the amplifier cannot supply a fixed current to an arbitrarily high load resistance."
