1 kHz Audio Oscillator


 This circuit consists of a CMOS square wave oscillator on a frequency of approximately 1 kHz.  The RC filter, which has a roll-off frequency of 500 Hz, filters the harmonics, providing a sine-wave output.  The oscillator has many uses sidetone circuits in transmitters and signal injectors for audio tests are just two.

The image below shows the schematic diagram for the oscillator.
