Abstract: A trimming structure for trimming functional parameters of an Integrated Circuit - IC - (100) comprising a first (115a) and at least one second functional blocks (115b,...,115n) with which a first (Vrg,a) and at least one second IC functional parameters (Vrg,b,...,Vrg,n) are respectively associated. The trimming structure comprises respective trimmable circuit structures (205a,210a,...,205n,210n) included in the first and at least one second functional blocks, and trimming configuration storage means (110) for storing trimming configurations for the trimmable circuit structures. The trimming configuration storage means are such that a change in the trimming configuration for the trimmable circuit structure of the first functional block causes a corresponding change in the trimming configuration for the trimmable circuit structure of the at least one second functional block. In addition, the trimmable circuit structures are such that a change in the at least one second IC functional parameter in response to the corresponding change in the trimming configuration for the trimmable structure of the at least one second functional block is proportional to the change in the first IC functional parameter consequent to the change in the trimming configuration for the trimmable circuit structure of the first functional block.
