Abstract
A method of providing a constant current drive to a driver circuit (40) in a compensating bias circuit (10) includes the steps of providing a constant current source insensitive to process, supply voltage, and temperature variations and mirroring the constant current source to the driver circuit while adding no sensitivity to process, supply voltage, and temperature variations.
