A 1-nA 4.5-nW 289-ppm/°C Current Reference Using Automatic Calibration

This article proposes an ultralow-power accurate current reference that generates 1-nA current. Since an automatic calibration circuit periodically calibrates the generated current of the current reference, the current reference is able to achieve ultralow power consumption and high accuracy simulta...
