| Abstract: | By using the integrated circuit design concept,the miniaturization processing of the MIT's multi frequency and multi-channel weak signal's preamplifier and band pass filter is realized.The miniaturization preprocessing circuit (preamplifier and band-pass filter circuit)has a small PCB size,simple structure,high signal-to-noise ratio,reliable temperature performance,convenient debugging and maintenance.The paper focuses on describing the circuit design,calculation and reality about the preamplifier and band-pass filtering processing,and single board test at room temperature and high temperature,separation device compared with integrated chip circuit board,etc.The realization of the miniaturization circuit board is of high reference value for logging instrument pretreatment. |
