The frequency stability of this circuit should only be a
function of the external component tolerances.
Figure 4-5 shows the circuit for a pulse width modulator
circuit. It is essentially the same as in Figure 4-4, but
with the addition of an input control voltage. When the
input control voltage is equal to one-half VDD, operation
is basically the same as described for the free-running
oscillator. If the input control voltage is moved above or
below one-half VDD, the duty cycle of the output square
wave will be altered. This is because the addition of the
control voltage at the input has now altered the trip
points. The equations for these trip points are shown in
the input voltage variations can be increased by
reducing the value of R6 from 10k
Ω and conversely,
sensitivity will be reduced by increasing the value of
R6. The values of R1 and C1 can be varied to produce
the desired center frequency.
