All-CMOS temperature independent current reference

An All-CMOS temperature independent current reference circuit was designed by eliminating the mobility dependence term through the combination of a current source which is proportional to mobility and one which is inversely proportional to mobility by using a CMOS square root circuit. The test chip fabricated using a 2 /spl mu/m n-well CMOS process showed a 1.7% variation in the average for the temperature range 0 to 75/spl deg/C.
