2 DoubleCross™ Spreadsheets

A spreadsheet for a basic DoubleCross Class-AB Follower output stage - OOorg or Excel .

A spreadsheets Solver add-in tool is very powerful because it can find the best bias settings, for example, minimum distortion. Best settings done manually are almost impossible to find with a DoubleCross Class-AB stage because there are twice as many variables as standard Class-AB.

A User Guide explanation PDF can be downloaded (below).
