Transimpedance Considerations for High-Speed Operational Amplifiers

Texas Instruments

Published Date: 11/22/2009

Description

Designing high-resolution detection circuits using photodiodes presents considerable challenges because bandwidth gain and input-referred noise are coupled together. This application note reviews the basic issues of transimpedance design provides a set of detailed design equations explains those equations and develops an approach to easily compare potential solutions.
