Abstract: |
Improving efficiency of designing circuits and reducing complexity for match between input and output networks is realized through Pi type or T type network or degraded Pi type or T type network. Transition matrix is utilized to describe and calculate optimal input and output networks of amplification circuit. Active circuit unit containing transistor in negative feedback is described and calculated through scattering matrix, which then transformed to transition matrix and scattering matrix for integral amplification circuit. Standing wave ratio of input and output, gain, noise temperature and stability coefficient are calculated and optimized through scattering matrix for integral amplification circuit. Advantages of precision, high efficiency and convenience of the method is proved by execution of computer. |
