Abstract :
In this paper a basic, four-transistor, resistorless current reference circuit is described, aimed at implantable biomedical applications. The circuit takes advantage of two different thickness thermally grown gate oxides, which are available in most high voltage processes and in some of the latest sub-micron feature size processes. Current tuning is achieved by sizing the transistors accordingly.
