ثبت نشده
چکیده
The conventional sine wave oscillator circuits use phase shifting techniques that RC phase shift oscillator using op-amp in inverting amplifier introduces. Figure show a RC phase shift oscillator using Op-Amp with gain 5(Vo/Vi). My assumption : Circuit is generating a sine wave with a peak to peak voltage of 10v. Voltage stability, specifically the lack of, when using a resister divider is the issue The left two op-amps make a phase shift oscillator with sine wave output.
