Regarding FPGA based controller Touch Screen Panel

[akael]

Hello,

I want to implement a controller for touch screen panel that has 24 sensing channels RX , and 25 driving channels TX.

Reading this document (https://www.researchgate.net/public...te_for_Large_Mutual_Capacitance_Touch_Screens)

I learn about the conventional architecture controller system for TSP , I would like to implement my FPGA based controller. I understand that for the analog part i need to considerer analog multiplexer, integrator and ADC. I found a Analog Front End (AFE) AFE0064, it is a 64 channel where each channel has an integrator, it is for medical application. Or maybe is better to use analog multiplexer and use one integrator and one ADC.

I hope you can give me some address what is the best way to implement it.

Any suggestions and commentary is for me very helpful.

Thanks in advanced,
