Bias compensation method and system for minimizing process, voltage and temperature corner variations

A bias compensation circuit comprising:

• a compensation logic circuit operative to vary a bias current used in a current mirror to stabilize an output driver of a data transmission system;
• and
• said compensation logic circuit is responsive to an n-bit digital signal representative of a corner state of said output driver.

A computer readable non-transitory medium including instructions which when executed in a processing system cause the system to provide bias compensation in a transmission circuit comprising:

• varying a reference current by a varying impedance associated with differences in operational in operational parameters in a current mirror established between said reference current from a calibrated bias circuit and an output current of an output driver from said data transmission circuit;
• and
• adjusting the varying step in said reference current by differences between said data transmission circuit and operational parameters.
