ASYMMETRIC OUTPUT DRIVER

This abstract first appeared for US patent application 18435329 titled 'ASYMMETRIC OUTPUT DRIVER

Original Abstract Submitted

A system and method for operating an output driver are disclosed, the method comprising connecting a first P-channel field-effect transistor (PFET) between a supply voltage and an output node; connecting a second PFET in parallel with the first PFET between the supply voltage and the output node; connecting a first N-channel field-effect transistor (NFET) between the supply voltage and a gate of the second PFET; and adjusting a voltage at a gate of the first NFET based on a voltage at the output node to modulate a voltage of a gate of the second PFET to maintain a pull-up resistance within a predefined range.
