Abstract
A reference buffer circuit comprises a dual-difference amplifier circuit including a first differential input, a second differential input, and a differential output that provides a differential reference signal; a first reference voltage coupled to a first input of the first differential input and a second reference voltage coupled to a first input of the second differential input; and wherein outputs of the differential output are connected by a feedback circuit path to second inputs of the first and second differential inputs.
