Phase 2 (±10V)
— V
SS transfer — Phase two of the clock
connects the negative terminal of C
2 to
the V
SS storage capacitor and the positive
terminal of C
2 to ground, and transfers the
generated –l0V or the generated –5V to C
3.
Simultaneously,thepositivesideofcapacitor
C
is switched to +5V and the negative side
is connected to ground.
Phase 2 (±5V)
— V
SS & VDD charge storage — C

is recon-
nected to V

3. The 5V charge from Phase is now
transferred to the V
SS storage capacitor. VSS
receives a continuous charge from either C
or C
2. With the C capacitor charged to 5V,
the cycle begins again.
Phase 3
— V
DD charge storage — The third phase
of the clock is identical to the first phase
— the charge transferred in C
produces
–5V in the negative terminal of C
, which
is applied to the negative side of capacitor
C
2. Since C2
+
is at +5V, the voltage potential
across C
2 is l0V. For the 5V output, C2
+
is
connected to ground so that the potential
on C
2 is only +5V.
