Abstract(in English) When some stages of amplifiers are driven by single source power, the undesired feedback loop may be formed via the feedline of the power. Then an unexpected feedback circuit may be constructed. Model of feedback circuit and design method for suppression of oscillation are needed because suppression of oscillation by using decoupling element could cost. In this study, calculation method of feedback circuit using loop gain for model amplifier is proposed. Calculated feedback circuit could suppress oscillation for model amplifier, it is comfirmed that proposed method is available for the design methodology.
