SINE WAVE OSCILLAT OR
By varying the previous state-variable filter topology slightly,
one can obtain a very low distortion sinewave oscillator with
programmable frequency feature as shown in Figure 11. Again,
DAC B and DAC D in tandem control the oscillating frequency
based on the relationship f
C
= 1/2
π
RC. Positive feedback is
accomplished via the 82.5 k
and the 20 k
potentiometer.
T he Q of the oscillator is determined by the ratio of 10 k
and
475
in series with the FET transistor, which acts as an auto-
matic gain control variable resistor. T he AGC action maintains
a very stable sinewave amplitude at any frequency. Again, only
two ICs accomplish a very useful function.
At the highest frequency setting, the harmonic distortion level
measures 0.016%. As the frequencies drop, distortion also drops
to a low of 0.006%. At the lowest frequency setting, distortion
came back up to a worst case of 0.035%.
