Hi,
I am having a challenging situation with detecting an oscillation on a DC voltage. My DC voltage varies from 0.2V to 3.1V and may have a 90kHz noise of 30mV in normal operation. In some fault situations, noise becomes 100mV with frequency is still 90kHz. I am trying to design some comparator based circuit to generate a high output if peak-peak voltage is more than 70mV.
Please help me if any one have some ideas.
Thanks in Advance;
Umesh
