Abstract
A bias circuit with an input current having a first reference node, the input current being gain divided to form a current smaller than the input current by a magnitude of the gain. The gain divided current being transferred through an intermediate current mirror with optional gain and to provide an output current. The output may have a second reference node that is different in voltage to the reference node of the input current, and multiplies the gain divided current by a gain so that the output current has a value equal to or greater than, but proportional to, the input current whereby an impedance in the output reference node is not reflected back.
