I'm trying to amplify a low signal with square pulses at 20 mV using op amps. According to simulation, rise and fall time of pulses increase too much after amplification, approximately 60 us. The component which will receive the signal accepts maximum 300 ns, the datasheet says so.
What kind of things can be done to reduce rise/fall time after amplification or to solve this problem? If I should choose another op amp, which is the best for this purpose?
I have another solution in my mind but I'm not sure. If I shift reference clock a little bit so that rising edges of clock don't meet the rising edges of signal(which are too long), will it work properly?
