Hi everyone
I need a sine wave generator preferably using the TL 071 opamp. I will accept any frequency from 100 hz to 10 Khz , supply voltage can be from 5volt to 18 volt. I have tried to simulate several designs, including the wien bridge, and twin t and phase shift, with no results. I would prefer to use the phase shift design. I would also prefer to use the spit supply design using positive, negative, and zero. First of all I’m using Circuit Maker to simulate the designs which does not have the TL071 in the library. I know that using the inverted input of the opamp will give me 180 deg. Phase shift at the output, then this is fed through another RC network for the other 180 deg , but to calculate the RC values for the other 180 deg and to consider the gain of the amp is where I’m having the problem. The circuit below is the one which I have been simulating. Can anyone help with the design or the formula or an opinion? Thanks
