    Hello everyone! i am pretty much new to this forum, and i would like to ask help from you guyz...

    i am trying to design a wien-bridge oscillator for me to have a Sine wave oscillator and i am having problems Simulating it... i am currently using Multisim ver 10.1... i have also tried the phase shift oscillator but it only gives me close to 0V DC output voltage...any hep please?

    Attached here is the diagram of the wien bridge. I have tried to increase 10k ohms resistor in the voltage divider to 15k to have a closed-loop gain more than 3...but still there is no oscillation, only that negligible output vtlage. Please help!

    Hello ochiboy,
    Welcome to AAC forum...
    I've tested many circuit simulator softs and conclude that multisim is the best one...
    As i remember Multisim provides readymade ckt of wien try it and debug yours..
    still any problem accors you can ask us..
