Here's a Circuit Design Idea fresh to the site - Locked-sync sine generator covers three decades with low distortion (click on the circuit diagram to expand it).It covers a sine-wave generator that can synchronise a sine-wave output through three decades of frequency and maintain low THD and constant amplitude.
The Design Idea begins:
Analogue applications, such as testing, calibration, and general system operation, often require a sine waveform of accurate amplitude and frequency, with low THD (total harmonic distortion). Some applications demand that the generator of such waveforms have the ability to accurately synchronize the output with an external timing signal.
Simple sine-wave generators can offer various degrees of this performance, but maintaining low THD with constant amplitude is a problem, particularly if the output and the synchronization signal must remain locked through an extended range of frequencies.Read the full Circuit Design Idea
