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