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