Voltage Controlled Oscillators
The classic Triangular/Square Wave VCO of Figure 15 is
one of a variety of Voltage Controlled Oscillators which may
be built utilizing the LM13600. With the component values
shown, this oscillator provides signals from 200 kHz to below
2 Hz as I
is varied from 1 mA to 10 nA. The output ampli-
tudes are set by I
x R
. Note that the peak differential input
voltage must be less than 5V to prevent zenering the inputs.
A few modifications to this circuit produce the ramp/pulse
VCO of Figure 16 When V
is high, I
is added to I
to in-
crease amplifier A1’s bias current and thus to increase the
charging rate of capacitor C. When V
is low, I
F
goes to
zero and the capacitor discharge current is set by I
C
.
The VC Lo-Pass Filter of Figure 11 may be used to produce
a high-quality sinusoidal VCO. The circuit of Figure 16 em-
ploys two LM13600 packages, with three of the amplifiers
configured as lo-pass filters and the fourth as a limiter/
inverter. The circuit oscillates at the frequency at which the
loop phase-shift is 360 or 180 for the inverter and 60 per
filter stage. This VCO operates from 5 Hz to 50 kHz with less
than 1% THD.
