Abstract :
Multipliers & dividers provide two basic operations essential in analog computers and also have many applications in fuzzy-control, instrumentation, analog signal processing, automatic gain control, frequency translation and etc. This paper is intended to implement voltage multiplier & divider using compensated log and antilog amplifiers. Here we discuss about the design of log & antilog amplifiers and problems involved in the log & antilog amplifiers and various causes that may affect the performance of log & antilog amplifiers. Finally different types of compensation techniques for the log & antilog amplifiers are discussed. With that we have designed the voltage multipliers & dividers, and simulation results of analog signal multiplication and division are plotted using NI Multisim 11.0.1.
