A Programmable Bias Source for the PJVS in the BIPM Kibble Balance

This paper describes a bias source that has been developed to configure the Programmable Josephson Voltage Standard used in the BIPM Kibble Balance. It has thirteen channels based on thirteen current sources with floating output. The operation of the bias source has been verified with PJVS system, exhibiting accuracy on the reference voltage at the \pmb10
^-8
level.
