ABSTRACT:
A band-gap voltage reference having reduced output voltage noise. The invention embraces several novel concepts, including the optimization of transistor area ratios as used in the band-gap device, the selection of multiple transistors in the Vbe, the section of the current range for the band-gap device, resistive loads to provide minimum load noise and selective signal filtering before the output amplifier. The resulting device according to the present invention exhibits lower output voltage noise than previous band-gap voltage references, without sacrificing other important voltage reference parameters, such as line regulation, load regulation, temperature coefficient, and stability.
