摘要
ADC前端是确定模数转换器接收和采样的信号质量的关键部分,基于对双通道模数转换器AD9268前端调理电路的设计、参考时钟的考虑,利用变压器进行匹配耦合设计,得到一个高性能的模拟前端ADC。
ADC is the key part in signal receiving and sampling circuit of analog-to-digital converter. This article introduces how to produce a high performance ADC circuit using AD9268 with properly designed pretreaunent, reference clock and transformer-roach-coupling circuit.
