Abstract
Apparatus and associated methods relate to a power supply noise disturbance rejection circuit (NDRC) having a first circuit reference potential (CRP), a second circuit reference potential (CRP), and a galvanic link conductively connecting CRPand CRPand providing a non-zero resistance return path for at least one current mode signal (CMS). In an illustrative example, a power supply monitor circuit (PSMC) may be referenced to CRPand a control circuit to CRP. The PMSC may, for example, generate a voltage mode signal (VMS) relative to CRPand representing an output parameter of a power supply circuit (PSC), and convert the VMS into a first CMS (CMS). The control circuit may, for example, generate a control signal for the PSC from CMS. Various embodiments may advantageously attenuate a noise margin of a CMS presented at the control circuit by a factor of at least 10 relative to an equivalent VMS.
