Study Notes
Operational Amplifiers (Op-Amps)
- The primary characteristic of an operational amplifier (op-amp) is that it provides high gain, high input impedance, and low output impedance.
Gain Characteristics
- The gain defined as the ratio of the change in output voltage to the change in input voltage is the open-loop gain.
Output Voltage
- The output potential of an operational amplifier (op-amp) is referenced to the circuit ground.
Amplifier Circuit Types
- In a non-inverting amplifier circuit, the input signal appears at the output with the same polarity.
Ideal Op-Amp Applications
- The following circuit is typically associated with the application of an ideal op-amp: non-inverting amplifier.
- The circuit that is not typically associated with the application of an ideal op-amp is the follower circuit.
