REVERSING GATE VOLTAGE REFERENCE DEVICE AND USING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a voltage reference device whose accuracy does not fall due to an environmental temperature.SOLUTION: A voltage reference device includes: a reversing gate transistor M1 that is disposed to receive a first current I1; a first transistor M2 that is disposed to receive a second current I2, has a first leakage current, and is connected to the reversing gate transistor M1 in a Vgs subtractive arrangement; an output node that is disposed to output a reference voltage, and includes an output node VREF connected to the first transistor M2; and a second transistor M3 that is connected to the output node, and has a second leakage current substantially equal to the first leakage current.
