Abstract
Signal-folding converters which establish two so-called fold analogue signals, whose curves of variation as a function of a voltage Vin to be converted cross over at multiple points. The architecture establishes n pairs of voltages varying with Vin and crossing over for regularly distributed values Vin=V,. At least two current routing circuits are provided, each of which possesses at least three pairs of inputs and at least two outputs including a direct output and an inverse output. The direct outputs, linked together, provide a folded signal SR; the inverse outputs provide a complementary folded signal SRb. Each routing circuit receives three voltage pairs of rank k−1, k, and k+1 and includes a current source supplying a group of branches arranged as a tree-like structure. The apportioning of the current in each branchoff depends on the voltage pairs of rank k−1, k, and k+1, and the direct and inverse outputs of the circuit are tapped respectively from two different branches of the last stage of the tree-like structure.
