摘　　要：针对大多数电压源分辨力不高或者分辨率达到要求,但是仪器的体积却过于庞大,从而造成开发、生产的成本比较高的问题,设计了一种多通道高分辨力程控电压源,电压源输出稳定性好,准确度高,各项参数指标较好,具有良好应用前景.For most voltage resources are not very good, or the size of the instrument is too large, and this can give rise to increasing the cost of development and production. This design is to design a more accurate multichannel programme voltage resource. Its precision and output stability is very good, all parameters index up to the requests, so it has wonderful application.
