CMOS multifunctional computational structure with improved performances

An original multifunctional structure with improved performances will be presented. The great advantages of increased modularity, controllability and of the associated reduced design costs represent an immediate consequence of multiple functions that could be implemented by the proposed structure: amplifying, multiplying, squaring or simulating positive and negative resistances. The circuit accuracy will be strongly increased by implementing original techniques, while the silicon occupied area per realized function will be reduced as a result of the multifunctionality. The estimated performances are obtained for an extended range of input voltages, the proposed multifunctional structure being designed for a low-voltage low-power operation.
