Producing and manipulating the sine wave function is a com- mon problem encountered by circuit designers. Sine wave circuits pose a significant design challenge because they rep- resent a constantly controlled linear Oscillator Sine wave circuitry is required in a number of diverse areas, including Audio testing, calibration equipment, transducer

drives, power conditioning and Automatic test equipment (ATE). Control of frequency, amplitude or distortion level is often required and all three parameters must be simultaneously controlled in many applications. A number of techniques utilizing both Analog and digital ap- proaches are available for a variety of applications. Each individual circuit approach has inherent strengths and weak- nesses which must be matched against any given application (see table).
