13. Quaternary digital to analog converter / Conversor digital quaternario para analogico
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 less

14. Analogic memories characterization implemented with floating gate MOS transistors / Caracterização de memorias analogicas implementadas com transistores MOS floating gate
Monolithic integration of memories and analog circuits ,in the same die offers interesting advantages like: smaller application boards, higher robustness and mainly lower costs. Today, a profitable integration of these kind of circuit can only be possible using conventional CMOS technology, which allows efficiently extraordinary levels of integration. Thus,

15. Fonte de tensão de referencia ajustavel implementada com transistores MOS / Adjustable voltage reference source implemented with MOS transistors
Uma nova técnica de compensação de temperatura para implementar tensões de referência em circuitos CMOS é descrita, desde o seu fundamento teórico até a comprovação experimental feita com amostras de circuitos integrados protótipos que a implementam. A ténica proposta se baseia no fato de que a tensão entre gate1, e fonte, VGS, de um transistor

16. Simulação analogica de linhas de transmissão utilizando-se circuitos integrados
The main goal of this work was the development of a didatic tool, based on integrated circuits, for the analog simulation of transmission lines. The obtained results allow for a quantitative analysis of the currents and voltages along the line. Initially, a study of transmission line models were carried out. As the circuit was implemented with operational am
