Abstract
Current circuits, circuits configured to provide a bias voltage, and methods for providing a bias voltage are described, including a current circuit configured to receive a reference current and having an output at which an output current is provided. One such current circuit includes a first current mirror configured to receive a first portion of the reference current and further configured to mirror the first portion of the reference current to provide a first current. The current circuit further includes a second current mirror configured to receive a second portion of the reference current and receive the first current. The second current mirror is further configured to provide a portion of the first current to the output of the current circuit as the output current and to receive another portion of the first current and mirror the same as the second portion of the reference current.
