%X The Ant Colony Optimization (ACO) algorithm is used as a multi-objective optimization technique to size a most popular analog circuit, the CMOS operational amplifier (Op-Amp). The work consist of finding the more convenient transistors sizes, including the channel widths and lengths, in order to meet or reach the specified requirements such as the voltage gain Av, the Common Mode Rejection Ratio CMRR, the die area A, the power consumption P and the Slew Rate SR. SPICE simulations are used to strengthen and to validate the obtained sizing/performances.
