Proposed buck converter includes load current sensing circuit to compensate load regulation. Because error amp has finite gain, there is load regulation in SMPS. In this paper we use variable current source that is added to positive input of comparator and current of current source is changed by sensed load current. The simulation result shows that proposed buck converter has improved load regulation than conventional buck convertor.
