i have an inverting amplifier circuit in clap switch project , it's dc output is full supply voltage although non inverting input is biased to half supply , i checked the circuit the feedback is connected correctly . any help
thanks
Your output of 555 (p3) is directly connected to Vcc (12V). Q1 would be conducting all the time.
Some of the junction dots are in the wrong places too. May be there are some other mistakes that I have not yet spotted. I think you need to improve the schematics so it can simulate properly.
