Can someone help me find an opamp similar to the TI OPA858 or OPA656 which can be used to amplify a small voltage signal into a signal which later can be used to be fed into a comparator?
Here is an example where a small 30mV voltage signal is amplified and later feed into a comparator for further processing. Can someone help me understand how I could achieve this? I tried different opamps in the ltspice library but haven't been lucky to et even the signal amplified - it is not at the moment a concern about the high frequency (5.5GHz) just want to understand how to get a simple voltage amplified.
Thank you very much.
