Abstract: An improved first order temperature compensated reference current generator. It comprises a current device providing a controlled current, a startup circuit connected to said current device for initiating operation of said current device, and a current definition mechanism driven by said current device for supplying a current which is independent of temperature, process and individual temperature coefficients circuit elements used. The said current definition mechanism incorporates voltage controlled resistors driven by a predetermined voltage and having a predetermined temperature coefficient.
