devices are required in order to make the capacitors start
at the inital value of 0v or 10v respectively.

The initial condition (.IC)
devices are placed in this
circuit to give the SPICE
simulator a starting point for
the outputs. This allows the
simulation to begin more
quickly. Since the circuit is
not exactly symetrical (the
capacitors are not the same),
SPICE could begin the
oscillation, but it would take
a few moments to get it
started.
Remove the .IC devices and try
it!

The rail voltage (15V) is multiplied by
each set of 2 diodes and 2 capacitors.
Two sets have been used in this circuit
resulting in a -30VDC (approx.) output.

The series and parallel RC
networks (R2+C1 and R3+C2)in
this circuit determine its
oscillating frequency. The
value of R1 sets the circuits
gain. If the gain is close to 3
D2 (R1=2*R4) a sine wave will be
R5
1N914 produced. If the gain is
12k
greater than 3, the output will
begin to clip. If the gain is
R1
less than 3, oscillation die
50k 60%
out. Try using the script STEP
VALUE function to vary R1 and
view the output results.
