Combined Positive Supply
Multiplication and Negative
Voltage Conversion
Figure 3-4 shows this dual function circuit, in which
capacitors C1 and C2 perform pump and reservoir
functions to generate negative voltage. Capacitors C3
and C4 are the respective capacitors for multiplied
positive voltage. This particular configuration leads to
higher source impedances of the generated supplies
due
to
the
finite
impedance
of
the
common
charge-pump driver.
