Circuit Project Electronic

Generates very low-distortion sine waves up to 1V RMS
No thermistors required - No settling time
Producing low-distortion sine waves, this oscillator operates over the range 16 to 22000 Hz.
The circuit is based on two articles that have appeared earlier in Wireless World - Roger Rosens’ “Phase -Shifting Oscillator”, February 1982 pp. 38-41, and J. L. Linsley [...]
