Abstract :

 Analog multiplication of two signals is one of the most important applications in signal processing. The main motivation for choosing an analog current multiplier is its importance in the function of nonlinear analog signal processing. The multiplier is used as a programming element in systems such as filters, neural networks, and as mixers and modulators in a telecommunications system. And are widely used in end-of-life frequency modulation conversion control filters for fuzzy integrated systems and so on. Quadruple multiplication has a non-linear function in signal processing that is very useful for communication equipment and control systems, and CMOS technology is widely recognized as the most desirable technology for implementing integrated circuits. Therefore, comparison and evaluation of current quadruple multipliers in terms of power consumption, total THD harmonic distortion, frequency response, linearity, speed, input voltage range, input current range, noise, power supply, and other parameters affecting quadruple current multiplier circuits are necessary to achieve a multiplier with proper performance and use in specific applications.
