7.2.1.1 Design Requirements

The main design requirements for wideband current-feedback operation are to choose power supplies that satisfy common-mode requirements at the input and output of the device, and also to use a feedback resistor value that allows for the proper bandwidth when maintaining stability. These requirements and the proper solutions are described in the Detailed Design Procedure section. Using transformers and split power supplies can be required for certain applications.
