A Comparative Study of Chinese and Foreign Textbooks on DC Analysis for Four-resistor Bias Common-emitter Circuit

The four-resistor bias common-emitter circuit is a kind of common-emitter circuits, which is very practical and can stabilize quiescent point very effectively. The interpretation of DC analysis for the four-resistor bias common-emitter circuit can be sorted as two methods in domestic and overseas textbooks. These two methods were introduced and discussed with a case of circuits design in the article. This article provides beneficial enlightenments for "Electrical Engineering" teaching material construction.
