  • Multiple output current mirror with improved accuracy
    Patent number: 6396757
    Abstract: A multiple output current mirror of improved accuracy suitable for use in a multi-level memory or analog applications is described. A reference current is mirrored in number of branches to produce replicas of the original current without degrading the original current. Both the mirrored transistor, through which the original current flows, and the mirroring transistors, which provide the replicated currents in each of the branches, are subdivided into a number of separate transistors. The effective channel width of a corresponding original transistor is shared among the transistors forming its subdivision. These subdivided elements are then physically arranged into a number partial current mirrors whose outputs are combined to form the total current mirror.
    Type: Grant
