Application of Superposition Theorem in Basic Voltage Amplification Circuit
Sun Yan-xia · Journal of Electrical & Electronic Education · 2012
Basic voltage amplification circuit is important content of analog electronic technology.The teaching method that superposition theorem is applicable to amplification circuit is studied.While the bipolar junction transistor in amplification circuit is constrained to its amplification region,the amplification circuit under small signal may be assumed a linear circuit to perform circuit analysis.The total voltage and current responses of each polar are sums of the individual responses from superposition theorem.An individual response is the result of an independent source acting alone.The students can easily understand and grasp the voltage amplifier analysis by the teaching method.
