3.4

Cascading Devices

To produce greater negative magnitudes of the initial

supply voltage, the TC1121 may be cascaded (see

Figure 3-2). Resulting output resistance is approxi-

mately equal to the sum of individual TC1121 ROUT

values. The output voltage (where n is an integer

representing the number of devices cascaded) is

defined by VOUT = -n (VIN).

3.5

Paralleling Devices

To reduce output resistance, multiple TC1121s may be

paralleled (see Figure 3-3). Each device needs a pump

capacitor C1, but the reservoir capacitor C2 serves all

devices. The value of C2 should be increased by a

factor of n (the number of devices).
