The present invention provides an improved reference source. The reference source has reduced sensitivity to the input offset voltage of the amplifier components in the reference circuit. This is achieved by subtracting two currents at the reference output node such that the combined offset sensitivity is less than the corresponding offset sensitivity for only one current.
