Hi all,


I have attached an image of the relaxation oscillator circuit that i have designed. Here, I am not getting the square output. The output voltage is showing 0V. I have used LM741 opamp. Can anyone suggest me what is the problem with the circuit!!!???? .... I tried by changing the values of R1, R2 and R3..
Plz...anyone guide me..............
Thank you in advance
 

Applying negative feedback will not make it oscillate! Are you sure you have the inputs to the 741 the right way around.

Yeah.... actually to pin.4 i have given -15V only, but by mistake i indicated it as -5V......

Thank you for your help...its really worth-full... i tried for these values. Now i got a square wave output of ±14V.....:grin:
I am trying to design for different values...
Thank you once again...............:smile:
