I use log detector (like AD8318) for pulse detection application. Applying detector output to ADC and which is sampled at 20MSPS and use this samples for further processing.
I use ADC part AD9051 in single ended ,DC coupled mode as shown below.
Problem here is output of AD9631 is inverted compared to Vin (with DC shift )and hence I need to use one more inverting amp to make ADC input compatible with Vin.
Please suggest simple solution for problem?
