A sinusoidal to square wave generator circuit is shown and simulated in Proteus professional software. The input signal is a 0 to 5V, 1MHz sinusoidal signal and the output is a square wave signal of same frequency 1MHz and amplitude diminished square wave signal.

The circuit consist of two cmos hex inverters 74HC04, two 1N914 diodes and passive components. The circuit is illustrated in the book the art of analog electronics, chapter 3- Field Effect Transistors, page 158, Fig 3.64.
