摘　　要：阐述ADC的前端电路的设计,前端电路各部分的功能分析,以ADS830为例,设计出完整的前端电路,利用LTspice仿真软件验证前端电路的性能。仿真表明,前端电路很好地驱动ADC,极大程度降低噪声的影响。This paper describes the design of the front-end circuit of ADC,and the functional analysis of each part of the front-end circuit.Taking ADs830 as an example,it designs a complete front-end circuit,and uses LTspice simulation software to verify the performance of the front-end circuit.Simulation shows that the front-end circuit drives the ADC well,greatly reducing the impact of noise.

关 键 词：模数转换器 前端电路 驱动电路 滤波
