Phase 2 (

— V
transfer — Phase two of the clock con-
nects the negative terminal of C
to the V

storage capacitor and the positive terminal of C

to ground, and transfers the generated –l0V or
the generated –5V to C
. Simultaneously, the
positive side of capacitor C
is switched to +5V
and the negative side is connected to ground.

receives a
continuous charge from either C
. With
the C1 capacitor charged to 5V, the cycle begins
again.
Phase 3
— V
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
. Since C
voltage potential across C
is l0V. For the 5V
output, C
potential on C
