In a system for performing a dual mode single temperature trim upon an
electronic device to remove combined mismatch and process variation
errors, a dynamic element matching control is configured for enabling
dynamic element matching of components of the electronic device. A
process trim module is configured for performing a process trim to remove
a temperature dependant error from the electronic device while the
dynamic element matching is enabled within the electronic device. A
mismatch trim module is configured for performing a mismatch trim to
remove a mismatch error from the electronic device after the process trim
has been performed. The mismatch trim is performed on a portion of the
electronic device for which the dynamic element matching has been
disabled. Additionally, the mismatch trim is performed at substantially
an equivalent temperature to a temperature at which the process trim was
performed.
