Multiplication of two signals is one of the most important operations in analog signal processing. The multiplier is not only used as a computational building block but also as a programming element in system such as filters, mixers, synthesizers, converter and modulators in communication systems. These are also important for non-linear analog signal processing functions finding application in adaptive filtering, modulation, fuzzy integrated system, frequency translation, automatic gain controlling and neural network. Current multiplier can be designed either using transistor in linear region, in saturation region.
