Abstract :
This paper presents logarithmic amplifier based on operational floating current conveyor (OFCC) with both voltage and current modes of input. Logarithmic amplifiers are nonlinear circuits in which the output voltage is proportional to the logarithm of the input. Logarithmic circuits play a very significant role in many industrial applications. The logarithmic behaviour of the proposed circuit is demonstrated using SPICE simulations, with negligible error and good dynamic range.
