i am building a bubba oscillator with C=100n and R= 31k to give a 50HZ sine wave.i tried simulating it on proteus isis but it does not work but i hear simulators are not to be trusted so am going ahead to build it in real life.
My question is this,when reading about bubba oscillator i read that we have to amplify the signal because of attenuation or something.
I want to ask after building the circuit how do i amplify the output signal before feeding it to a comparator for generating a PWM signal.also this simulation softwares are funny atimes.is there anyone with experience on them.any further advice will be appreciated.thanks
