Abstract :
A low-voltage CMOS temperature-independent current reference is presented. The proposed circuit requires no external component for biasing. Temperature independent voltage is converted to current, and proper operation is guaranteed by a fast startup circuit. The reference current is designed scalable to allow changing the power consumption of the overall system dynamically. The circuit is fabricated in TSMC 0.18mum process and measurement results show less than plusmn100 nA variation between 22deg C and 100deg C.
