i tried to simulate a simple comparator(ic 741) design to produce a square wave at the output for the given sin wave(amp:6 freq:50)..what i am stuck is that the square wave is not fully generated .. it momentarily goes to Zero ..can u please explain why is this happening ?

Welcome to AAC!
  1. You're trying to use an opamp as a comparator; which it's poorly suited to do.
  2. You're using a 741 which has a number of limitations.
  3. You're operating it from a single 5V supply. So it's input and output range will be miserable.
  4. You're operating it outside of it's common mode input range.
