Abstract

A field programmable logic device features an active device driver employing CMOS circuitry that includes a complementary CMOS inverter in electrical communication with a tri-state CMOS inverter, with the tri-state CMOS inverter defining a data input and a data output of the active device driver. The CMOS complementary inverter has an input node and an output node. The CMOS tri-state inverter is coupled to the input node, defining a control input for the active device driver.
