A short-circuit charge-sharing technique which allows charge-sharing
between two or more circuits with a simple shorting transistor controlled
to achieve the desired operating voltage levels. The shorting transistor
which can be either a P-channel Metal Oxide Semiconductor (PMOS) or an
N-channel Metal Oxide Semiconductor (NMOS) device and can be controlled
utilizing the same clock that enables the drive of the signals between
which charge-sharing occurs. In operation, the desired operating voltage
levels can be regulated by increasing and decreasing the pulse width of
the control circuit output to the gate of the shorting transistor.
