RESUMO

This work presents the mathematical equations, simulations and detailed analysis of DC behavior, harmonic distortion, frequency response and input signal excursion of ten V-I converters, or tranconductors, that use MOS transistors on the saturation region of operation. Those transconductors are divided into four groups, which corresponds to the four chapters of the thesis. They are: Transconductors with Differential Pairs; Transconductors with Adaptative Biasing; Class AB Transconductors; Transconductors Designed at DEMIC/FEE-UNICAMP. Comments are done on each circuit, enhancing their positive and negative aspects, besides comparisons among transconductors of a same group. Suggestions and enhancement proposes are also realized, besides their verification by simulations
