Abstract
Control method of automatic gain control （AGC） for video amplifier and its advantage and disadvantage are analysed in this paper. Combined with fault discovered in application, AGC circuit is improved. Through circuit simulation and testing, the results show that the improved circuit not only ef- fectively improves the input dynamic range of video amplifier, but also can suppress influence on AGC cir- cuit from the leaking signals.关键词
