This TI Precision Labs - Op Amps training video provides a detailed analysis of the internal transistor structure of a current-feedback amplifier to explain why current-feedback amplifiers are able to achieve very high slew-rates. We'll also explore the noise and input bias current of a current-feedback amplifier. Finally, we'll compare current- and voltage-feedback amplifiers, examining the strengths and weaknesses of each and how to decide which is the most appropriate for your system design.
