摘要
分析并计算了差动放大器的噪声性能及抗干扰能力,说明带恒流源的差动放大器在高灵敏度的自动化仪表及检测装置中,作为前置放大器是很合适的。
In this paper the noise performance and interference-free ability of differential amplifier is analysed. According to the analysis, differential amplifier is good for being pre-amplifier in automatic device and instrument of high senstivity.
