Compensating Current Feedback Amplifiers in Photocurrent Applications

Blog Post created by analogkidr on Sep 10, 2013

Current feedback amplifiers (CFA) are not typically used as transimpedance amplifiers due to their relatively high inverting input current and current noise. CFAs are easy to use, however, and can outperform their voltage feedback counterparts in applications that require high gain, low power, low noise, wide bandwidth, and high slew rate. This article shows how to properly compensate CFAs.
