Hi All,


I have cascaded detector (AD8138) and comparator (ADCM601). output of detector's max voltage is 2 V with this configuration. After I added limiting amplifier in front of detector, I got 1.2 V at output of detector.

Somehow configuration betseen limiting amplifier and detector caused this problem?

What should be done to increase output voltage of detector?

I also summarized at attachment.
