Abstract
A cascode bias circuit biases a gate of a cascode transistor in a cascode current mirror. The cascode bias circuit includes a first transistor configured to conduct a first current and includes a second transistor configured to conduct a second current. The first and second transistors couple to a third transistor configured to conduct a sum of the first current and the second current. A gate of the first transistor couples to a gate of the cascode transistor to bias the cascode transistor.
