SHORT-CIRCUIT CHARGE-SHARING TECHNIQUE FOR INTEGRATED CIRCUIT DEVICES

摘要

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.
