Low voltage, fast settling precision current mirrors and methods. The precision current mirror have first and second current mirrors, each having an input to be mirrored and a mirror output, the current mirrors being coupled so that the mirror output of each current mirror receives part of the input to be mirrored by the other current mirror, the first current mirror also mirroring current for re-mirroring to the input of the second current mirror, and to a precision current mirror output in proportion to the current provided to the input of the second current mirror. Various embodiments are disclosed, including MOS and junction transistor embodiments, and an embodiment having increased output impedance.Details of the method are disclosed.
