The simple square wave generating circuit of TL082

Published:2011/6/14 3:32:00 Author:Borg | Keyword: square wave, generating circuit | From:SeekIC

This circuit is a rectangular and square circuit, the time of the high/low LEV can be set separately, the oscillating frequency is decided by high and low LEV time. In the circuit, the resistors which decide the charging/discharging time of capacitor C are shifted by diodes, and the square wave high/low LEV time can be regulated by changeable resistors R1 and R2. The resistance net RA is the feedback circuit and the charging/ discharging circuit of capacitor C for the op-amp. The output voltage of the op-amp is split by the resistors of 56kΩ and 47kΩ and becomes the reference voltage, it compares with the voltage on capacitor C and then generates the oscillation.
