摘要
A current mirror circuit includes an input portion configured to conduct a bias current, and a first current source circuit coupled to the input portion and configured to generate the bias current, and vary the bias current over a range of currents based on a first group of weightings associated therewith. The current mirror circuit also includes an output portion configured to conduct an operational current, wherein the output portion is coupled to the input portion, and a second current source circuit coupled to the output portion and configured to generate the operational current, and vary the operational current over a range of currents based on a second group of weightings associated therewith. The first group of weightings and the second group of weightings are different.
