Sine wave oscillator can be implemented using Wien-Bridge oscillator like in our previous sine wave oscillator circuit, but now we present another method of generating sine wave signal. Using phase shifter, we can build a simple sine wave generator, as shown in the schematic diagram below:

sine wave oscillator phase shift circuit schematic

Sine wave oscillator using phase shifter has lower distortion than Wien-Bridge oscillator, coupled with good frequency stability. The drawback is that the phase shift sine wave oscillator neeed more components (resistor and capacitors). [Source: Texas Instruments Literature]
