Schmitt trigger problem

  1. Mar 27, 2007 #1
    i'm new here. currently, i'm having a problem with pspice simulation. i'm design a schmitt trigger using cmos but when i run it, the forward and reverse switching voltage does not appear. how should i do to make the hysteresis appear in the output simulation waveform? please... i need it urgent..

    Are you still having this problem? Can you post your schematic or SPICE deck?
