Figure 1 shows how a three phase sine wave oscillator can
be built using one UAF42 state variable filter along with
some resistors and diodes. Three output nodes are available;
highpass out, bandpass out and lowpass out. The signal at
the bandpass and lowpass out nodes are 90° and 180° out of
phase, respectively, with the highpass out node. An on-chip
auxiliary op amp is available for use as a buffer or gain
stage.
