Abstract
This thesis describes the design and realization of a power operational amplifier built of discrete component parts. Its supposed aplication is in output-stage of four-quadrant power supply. The operational amplifier design is depicted piecewise. Especial patient is applied on modified source / sink AB output stage. The design module has been realised, dubugged and measured. The static and dynamic measurements results are presented and compared to datasheet´s data of integrated operational amplifier OPA549 with similar features.
