Abstract
The design and major applications of a general purpose current mode bu ilding block are presented in this paper. This circuit is basically a high gain transconductance scheme with differential current output ter minals previously termed operational floating amplifier (OFA). The nov el structure proposed here is shown to implement a very flexible and h igh performance amplifier which can be used in almost all applications employing conveyors, current feedback amplifiers or even conventional operational amplifiers with improved performance characteristics. Thi s presentation is also supported by experimental measurements on a pro totype circuit realized in CMOS technology.
