Abstract :
In order to improve the accuracy and stability of conventional least square estimation for noise power spectrum, this paper presents a new method of quantitative calculation which is based on the squared distance minimization (SDM). The amplitudes of each noise can be gained by using this method, and then the reliability estimation of the semiconductor can be realized. The experiment results show that the SDM method is more stable and need less computation than that of the least square method (LSM).
