2 variants:

1 - Yours, external components required.

2 - use Mixer

Signal must be greater than 0 and less than VddDet.jpg

Dear EvPa_264126,

Thanks for your support!

In the first way: it is necessary to have additional external accessories such as resistors and diodes. I thought the diodes and resistors would be in PSoC.

In the second way: it shows when there is a peak, but not the amplitude of the peak. What I want is to keep the amplitude of the signal.

Thanks,

Hai Lai
