Abstract
In an I/O driver, noise reduction is achieved while maintaining good performance, by providing a conventional output driver leg and a secondary output driver leg, the primary output driver leg comprising a primary predriver and a primary output driver, and the secondary output driver leg comprising a secondary output driver having a common output with the primary output driver, wherein feedback from the common output is fed through a pair of pass gates that control the secondary output driver.
