RESUMO

In this work is presented the multiple value logic as option to substitute or to be used as interface with the binary logic. The multiple value logic differs of the classic binary logic to the fact that its digits are beyond zeros and ones. Using the multiple logic value obtains communication in between blocks or with the external world to one chip with lesser number of interconnections, what it will cause the reduction of the area of the integrated circuit and reduction of costs. Researchers and industry walk for the research and development of multiple values circuits, that can substitute or be used as interface with the circuits of two values (binary). This work presents the developed one of the project of a quaternary digital to analog converter that it has four inputs and resolution equivalent to a binary digital to analog converter of eight inputs. This converter was confectioned totally in technology CMOS 0.35µm, having as resulted an prototype of an integrated circuit multiple value that contains all the cells of a binary digital to analog converter. This converter presents consumption of power below of 1mW, simple voltage of 5V and compacting (900µm x 235µm)
