Abstract
The present invention comprises methods and circuits for mirroring input current in multiple stages to improve the accuracy of the mirrored output current over a wide dynamic range of input current. The current mirror circuit of the present invention automatically (1) detects an increasing magnitude of input current and (2) adapts the current mirror circuit to accommodate the increasing magnitude.
