چکیده

In real world signal processing systems, the operational amplifier is the main block for detecting the analog signal. This paper presents a multi optimization technique for the optimal sizing of Transconduc amplifier. By using multiCMOS folded cascode operational transconductance amplifier that operates at low voltage is designed for signal processing application. The MOGWO is a swarm intelligence based optimization algorithm has ability to explore the search space of an optimization problem. The objective functions and user defined specifications of proposed circuit can be modeled as optimization problem. The proposed method is a model based design optimization technique used to generate the transistor size and input bias current in an amplifier circuit. This paper mainly focuses on DC gain, unity gain bandwidth and slew rate of an amplifier without affecting other circuit performances. Finally, the optimally designed amplifier has 80.2 dB DC gain, 40 degree phase margin and 452 MHz unity gain bandwidth.
