Application ReportSLOA060 - March 20011Sine-Wave OscillatorRon Mancini and Richard PalmerHPL (Dallas)ABSTRACTThis note describes the operational amplifier (op-amp) sine -wave oscillator, together with thecriteria for oscillation to occur using RC components. It delineates the roles of phase shift andgain in the circuit and then discusses considerations of the op amp. A brief analysis of aWien-Bridge oscillator circuit is provided. Several examples of sine -wave oscillators aregiven, although it is recognized that there exist many additional types of oscillator to whichthe principles of this application note also . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2Sine-Wave Oscillator Defined3.
SLOA060 Sine-Wave Oscillator 3 1 Introduction Oscillators are circuits that produce specific, periodic waveforms such as square, triangular, sawtooth, and sinusoidal.
