Abstract
This paper presents a 10-μA, trim-free, low temperature coefficient, supply independent current reference with process compensation feature. Based on the proposed structure, a 130 ppm/°C temperature coefficient current reference across -40°C to 80°C temperature range is achieved. The proposed circuit can work at supply voltage varying from 2.4 to 3.0 V, while only has 30-nA drift at room temperature. The proposed current reference is implemented in 0.18-μm CMOS process occupying an area of 0.005 mm2.
