摘要

本文提出了一种10 μ a、无微调、低温度系数、具有过程补偿特性的电源独立电流基准。基于所提出的结构，在-40°C至80°C的温度范围内实现了130 ppm/°C的温度系数电流参考。该电路可以在2.4 ~ 3.0 V的电压范围内工作，而在室温下仅具有30 na的漂移。所提出的电流基准是在0.18 μm CMOS工艺中实现的，占地面积为0.005 mm2。

A low TC, supply independent and process compensated current reference

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.
