Charging/Discharing capacitor example. The initial condition

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.
