Abstract
An improved reference current generator for use in an integrated circuit. A voltage difference generator generates two voltages that are separated by a relatively small electrical potential. The two closely separated voltages are applied across a resistive element with relatively large impedance value resulting in a small and stable reference current. The stable reference current is mirrored and, if desired, amplified for use on the integrated circuit. A driver selectively drives state information off chip for assisting in post-silicon correction of unwanted sensitivities. A configuration memory stores values used to adjust effective device widths and lengths for correcting unwanted sensitivities.
