In order to develop good analog circuits, a basic understanding of the noise analysis is required. In this paper, we present a noise model for class AB CMOS current conveyor and show how the model can be used to evaluate the noise in the current conveyor. Finally, to check the validity of the proposed model all the theoretical results have been compared with simulation ones. For the thermal noise, comparison shows that the theoretical results are in excellent agreement with the simulation, being the error between 4 and 5%. Also for the flicker noise, comparison between theoretical and simulated results is presented. Again the difference between them is not high, being the error of about 8%.
