Abstract

See full text

Disclosed is a voltage reference buffer circuit including a first, second, third, and fourth bias generators and a first, second, third, and fourth driving components. The first, second, third, and fourth bias generators generate bias voltages to control the first, second, third, and fourth driving components respectively. The first, second, third, and fourth driving components are coupled in sequence, wherein the first and second driving components are different types of transistors and jointly output a first reference voltage, the third and fourth driving components are different types of transistors and jointly output a second reference voltage, and the group of the first and second driving components is separated from the group of the third and fourth driving components by a resistance load.
