Ovation nx-Amplifier: A 100 W class AB Current Feedback Amplifier
This power amp design is based on the sx-Amplifier topology, but with the TIS and output stage re-configured for class AB operation, enabling it to deliver 100 W into 8 Ohms. I have kept the design very simple, retaining the…
CFA vs. VFA: A short primer for the uninitiated – Extensively Updated January 2014
There are many explanations about IC CFA topologies like this or this. Some plunge into math, loop gain equations and so forth, leaving the reader none the wiser, while this one (equations 1~4 and associated gain plots) from Hans Palouda…
AN-597 Current Feedback Amplifiers
This National Semiconductor application note was written by Hans Palouda and published in 1989. It explains basic CFA operation clearly and concisely. AN-597 Current Feedback Amplifiers
