The sine wave forms a square wave with a duty cycle of 50%
If the input signal voltage of sine and cosine is high, through 5~ 10K resistor, two anti-parallel diodes are added at the inverting input terminal GND, and a voltage regulator (two anti-parallel diodes) is added between the inverting input terminal and OUT as limiting. Output by the OUT terminal.
