The spatial electronic field detector of the CSES satellites is applied to measure technical specifications of the electric field variation in the plasma environment of space. Under that situation,the requirement ofthe distortion,sensitivity, and dynamic range are strict, while circuit noise is the main factor that has an significant impact on its technical specifica-tions. Based on the characters of the circuit configuration, this paper establishes a noise model of the preamplifier, with which the noise level is calculated and simulated using TINASPICE. And the testing method of the circuit noise is introduced briefly.
