Here below is a simple comparator circuit, mean to go to Vsat with input being greater than threshold and when its less than threshold (25mv in my case) should be 0V, so i should see a pulsed digital output , changing its state with input pulsated waveform, but when i observe the behavior on TINA its quite abnormal, kindly suggest me changes to be done in my design file
find the attached design file and image
