Analogue Square Root Calculator Circuit Designed With Logarithmic Amplifiers

In many applications, it has been necessary to calculate square roots of some numbers which are correspond to some voltages values. In this study such an analogue calculator has been designed and simulated in computer medium. Circuit consist of one logarithmic and one antilogarithmic amplifier connected in cascade. The component values of circuit chosen so that the output voltage of circuit is equal to square root of input voltage. The performance of designed circuit is investigated by applying different voltages to the input of circuit. Such as analogue square root calculator circuit is faster than the other digital square root calculator circuits.
