I'm trying to design a schmitt trigger with positive and negative threshold of +15mV and -15mV, (V-high and V-low respectively). I'm planning on using the LM319N IC for its comparators. I have a cct that works well at kHz frequencies (in LTspice), but I don't get the outputs I want when working in the Mhz frequency range. I'm looking for some advice on how to modify my design or which commercial schmitt triggers to look at.
