摘　　要：旋转变压器作为轴角测量元件得到广泛应用，在计算机测控系统中，旋转变压器一数字转换器（以下简称R／D转换器）是将旋转变压器输出的模拟信号进行数字化处理，供后级电路采集处理。本文介绍的一种带激励源、并／串数字输出的R／D转换器电路．具有激励频率、数据输出方式可调，分辨率、速度电压可编程，精度高，功耗低，集成度高等优点。Resolver is widely used as the shaft angle measuring component. In the computer measurement and control system, the resolver-to-digital converter （hereinafter referred to as R/D converter） process the analog signal output from the resolver for the subsequent stage circuit acquisition. This paper introduces R/D converter circuit with excita- tion source and parallel/serial digital output. It has excitation frequency, adjustable data output mode, programmable resolution of speed voltage, also with the advantages of high precision, low power consumption and high integration.

关 键 词：R/D转换器、激励源、并/串数字输出
