Norton_sine_wave_oscillator

This circuit uses four sections of an LM3900 to form a sine-wave oscillator. One section is used as a gain-controlled amplifier (to sustain feedback), and another section is a difference averager that maintains a constant output level.The remaining sections are connected as an RC active filter (to produce a 1-kHz output with the values shown).
