This Thesis presents a design of the Folded-cascade operational amplifier which leads to high gain as compared to a normal cascade circuit. In this project; specifications of analog systems into op amp level net-lists of library components is studied and simulated using XILINX. As the power-supply voltages because of the technology improvement and it are desired to reduce power supply to minimize power dissipation, many challenges are faced by the analog designer. One is to keep noise level as possible. The op-amp must be designed to with the ever decreasing power supply voltages. As the power supply voltages begin to approach 2Vt, new technique and new op-amp topology like folded cascade should be used.
