| Abstract: | The thermal noise made by analog wideband amplifier has the characteristics of Gaussian white noise. Based on analog wideband amplifier,a design method of noise source module is proposed. This paper introduces the design scheme of this method and discusses in detail the problems to be solved in the design and their solutions, and analyzes the key techniques used in the design. The noise output from the noise module is tested and the test results are analyzed. The test results show that the signal generated by this method has the characteristics of Gaussian white noise. |
