| Abstract: | Most tradional analysis of the differential amplifiers in dynamic state is conducted under specific condition and based on the characterics of signals input and output. Conclusions can easily be drawn after such analysis, yet their physics implication is hard to get across. This constitutes one of the difficulties in recognizing and understanding the differential amplifiers. This paper derives indexes concerned from typical circuit and different linking methods so as to provide an approach to this problem. |
