Abstract
A reference buffer is disclosed. The reference buffer includes an amplifier configured to amplify a difference between a reference output voltage and a reference input voltage during a closed-loop phase of the reference buffer. The reference buffer also includes a sample circuit configured to sample an amplifier output voltage during the closed-loop phase. The reference buffer further includes a buffer circuit having a buffer input coupled to the sample circuit and a buffer output configured to provide the reference output voltage. The reference buffer also includes first and second switch circuits. The first switch circuit is configured to isolate the sample circuit from the output stage of the amplifier during an open-loop phase of the reference buffer. The second switch circuit is configured to isolate the input stage from the output of the reference buffer during the open-loop phase.
