Abstract
A reference buffer with wide output voltage and current range is provided. A reference buffer includes an error amplifier comprising a first input, a second input, and a first output, wherein the amplifier is configured to generate an output signal indicative of an error between an output reference signal and an internal reference signal. The reference buffer further includes a first voltage follower circuit configured to generate the output reference signal based, at least in part, on the output signal of the error amplifier, wherein the first voltage follower comprises a third input and a second output, and wherein the second output is coupled to the second input of the error amplifier.
