Derivation of the Complete Analytic Expressions for the Voltage Magnifying Factor of the Reversed Feedback Amplifier

FANG Tian-shen(College of Physical and Electronic Engineering,Xinyang Normal University,Xinyang 464000,China)  
Abstrcat In this paper,the analytic expressions of closed-loop voltage amplification factor(A_(vmf)) for the reversed feedback amplifier are derivated by circuit analysis,without using feedback coefficient.In the new expressions,the definition of fundamental magnifying factor for the 4 kinds of circuits is the same.They are easy to solve A_(vmf) in calculation,without considering the loading effect of feedback network any longer,and an unidirectional conversion can be made; meantime,they can directly describe the effect of every circuit component parameter on the closed-loop voltage gain.Moreover,the A_(vmf) approximation expressions which are more convenient to direct application can be derivated by these new expressions.
