Abstract

This seminar report discusses the low-voltage current-mode analog circuits and their various aspects. The need of high speed, high performance, low power circuits because of the advent of the portable electronic and mobile communication systems and difficulties faced in achieving that in today’s scenario are presented. Current mode circuits are the best suited candidates for the above. Their advantages are discussed here and a comparison with the conventional voltage mode circuits has been presented. The principle and the implementation of the most common current mode circuits i.e. the current conveyors, has been described. The basic device level techniques also play important role in the design of smarter and efficient circuits. Some of those techniques have also been discussed here. For illustration of these techniques, low power V-I converter using current mirrors and a low- voltage power efficient operational amplifier cell topology is presented
