ABSTRACT:
The present invention provides an analog biased pre-driver and pad as well as a duty cycle adjustment cell prior to the pre-driver and pad. The pre-driver and pad may operate in either a 3 volt mode, a 5 volt mode or any voltage in between depending only on the power supply voltage present. No production configuration or post-production configuration is required. The present invention utilizes a special bias circuit to reduce the Vcc, temperature and other processing variations. A duty cycle cell produces a range of duty cycles when the circuit is operating between a 3 volt and 5 volt range.
