Patent abstract
A power efficiency control circuit eliminates short circuit power consumption associated with a CMOS output buffer in a manner that substantially increases the buffer operating efficiency. The technique is implemented to allow for a reduction of power associated with the output buffer pre-driver stage. The methodology employs a power efficiency control circuit that tri-states the output buffer before every transition.
