Method and apparatus for a nonlinear current circuit element are described,
and method and apparatus using the nonlinear current circuit element in current-source
self-biasing circuits are described. In one embodiment, a transistor is provided
having source and drain terminals coupled together. This transistor has a significant
gate tunneling current used beneficially to provide a nonlinear current circuit
element. This nonlinear current circuit element is used in a plurality of current-source
self-biasing circuits.
