ABSTRACT:
An integrated circuit and method are provided for generating current for low power applications. The integrated circuit preferably includes a current generating circuit responsive to a supply voltage for generating a first reference current and a temperature compensating voltage controlling circuit for generating a temperature compensated voltage control signal during temperature variations. A bias controlling circuit is preferably connected to the current generating circuit and the temperature compensating voltage control circuit for biasingly controlling the temperature compensating voltage control circuit. A current output controlling circuit is connected to the current generating circuit and the temperature compensating voltage controlling circuit for controlling a second temperature compensated reference current responsive to the temperature compensated voltage control signal so as to generate a high output source current even during low temperature conditions.
