2024 – PAK celebrates 12 years!

What is PAK about? I wanted to solve the large signal equations for Audio Power Amplifiers.

This is "not possible" ... well, it wasn't possible until Robert Banwell's 2000 IEEE paper gave an analytical solution for a common emitter amplifier IEEE paper in T.CAS November 2000.

He broke the "transcendental barrier" as Barrie Gilbert called it, and gave us a large-signal solution.

So I thought, let's do this for audio Power Amplifiers and find their large-signal solutions.

It can be done for a DoubleCross output stageusing a spreadsheet. See PAK2024 .
Solver can find optimum the bias and THD can be plotted against output power!

I very much would like to hear from anyone interested in this approach. Use the Contact section. 

You can download a zip file with all the PAK Project spreadsheets, docs and LTspice files (20MB)
(it includes the original PAK1 2012 files and docs).
