Designs of a logarithmic and exponential amplifiers using current conveyors
A few solutions already exist to improve the dynamics of an image using the LIP model, but no in real time. To give a solution to that problem, we developed a fast and accurate logarithmic and exponential amplifiers thanks to current conveyors because the logarithmic and exponential operations are the main calculations in the LIP model. The original contribution of our work is to use current conveyors to design the amplifiers. Compared to the others amplifiers we got good performances in frequency response, and good independence to the temperature.
