    Let me count the ways:

    Schmitt Trigger
    Comparator
    Overdriven amplifier
    Threshold driven flip flop
    Clipper/differentiator/bistable multivibrator
    Odd harmonic multiplier/adder


    Shall we continue?

    However, probably the simplest and cleanest would be a simple comparator.

    i forgot to mention that i should use diode circuit only

    Thank you Bill Marsden for your reply
    but the final output has some slope. i need exactly square wave.

    Then you can't use diodes. You want exact, it needs to be active (ie, gain).

    Diodes clip the top and bottom off. You'll find all square waves have some slope, it is a function of frequency response. The actual term is slew rate.

    You can get a little sharper edges with Zener diodes, but they still aren't perfect....and they tend to be slow.
