7.2.2.1 Design Requirements

The main design requirements for Figure 7-4 are to match the output impedance correctly, satisfy headroom requirements, and confirm that the circuit meets power driving requirements. These requirements are described in the Detailed Design Procedure section and include the required equations to properly implement the design. The design must be fully worked through before physical implementation because small changes in a single parameter can often have large effects on performance.
