PARALLELING DEVICES
Any number of devices can be paralleled to reduce the output resistance. As shown in Figure 8, each device
must have its own pumping capacitors, C1 and C2, but only one shared output capacitor is required. The
effective output resistance is the output resistance of one device divided by the number of devices used in
parallel. Paralleling devices also gives the capability of increasing the maximum output current. The maximum
output current now becomes the maximum output current for one device multiplied by the number of devices
used in parallel. For example, if you parallel two devices you can get 20 mA of output current and have half the
output resistance of one device supplying 10 mA.
