TI Precision Labs - Op amps: Current-feedback amplifiers
What is a current-feedback amplifier, and when is it the best choice for your system design?
In this series, you will learn the main advantages of current-feedback amplifiers, namely:
- Bandwidth independent of closed-loop gain
- Very high slew rates
You will learn how to perform loop-gain analysis, also known as stability analysis, on a current-feedback amplifier and compare it to the loop-gain analysis technique for a voltage-feedback amplifier. Finally, you'll receive a comprehensive summary of these two amplifier types, which will enable you to select the best amplifier for your end-application.
