Part II - Basic Op-Amp Configurations
This part of the class explains the negative feedback in op-amp circuits and how to compute basic parameters for the basic op-amp configurations. You will learn how to:
- Analyze three op-amp configurations including inverting and non-inverting amplifiers, and voltage followers
- Describe impedances of these basic op-amp configurations
- Troubleshoot op-amp circuits.
- Op-amp configurations with negative feedback
- Op-amp impedances
- Troubleshooting op-amp amplifiers
- Non-inverting amplifiers
- Inverting amplifiers
- Voltage followers
- Closed-loop voltage gain
- The non-inverting amplifier has a minimum voltage gain of unity.
- An inverting amplifier can provide gain or attenuate the output.
- The output of an inverting amplifier is 180° out of phase with the input.
- A voltage follower always has a gain of 1.
- All op-amps have designed input and output impedances.
- The use of negative feedback has a major impact on the input and output impedance that can be far different than the design parameters.
Op-amps can be connected in closed-loop or open-loop configurations.
