Common-Mode Rejection
Common-mode rejection (CMR) is the ability of a
device to reject a signal that is common to both input
terminals. The common-mode signal can be either an
AC or a DC signal or a combination of the two. CMR is
often expressed in decibels.
Power-Supply Rejection Ratio (PSRR)
Power-supply rejection ratio (PSRR) is the ratio of the
input supply change (in volts) to the change in the
converter output (in volts). It is typically measured in
decibels.
