Stabilizing Current-Feedback Op Amps While Optimizing Circuit Performance

Texas Instruments

Published Date: 04/28/2004

Description

Optimizing a circuit design with a current-feedback (CFB) op amp is a relatively straightforward task once one understands how CFB op amps achieve stability. This application note explains a 2nd-order CFB model so that any designer can better understand the flexibility of the CFB op amp. This report also discusses stability analysis the effects of parasitic components due to PCBs optimization
