8551.PeakDetector.pptI am designing the peak detector circuit using THS4631. I have some problem. Before designing the circuit, I verified on the circuit on Tina and it shows working. But, I implemented on my board and can not have top peak voltage of signal. Here is my board and Tina schematic attached. As schematic shown, the first buffer is to extract signal with X5, which is no issue here. The second is the problem stage. I can not have negative or positive peak value. If you need more information, we can discuss with you on phone or through email.
Your help is really appreciated
Best regards,
Bon
