现代通信系统和测试设备常常需要尽快地将模拟信号数字化，以便在数字域中完成信号

处理。但是，为模数转换器(ADC)设计变压器前端电路很有挑战性，特别是在高中频(IF)

的系统中。本文总结了5 个设计步骤，以帮助开发出最佳的ADC 前端-The modern communication systems and test equipment often requires expeditiously the analog signal is digitized, in order to perform signal processing in the digital domain. However, the front-end circuit for analog-to-digital converter (ADC) designed transformer is very challenging, especially in the high intermediate frequency (IF) system. This article summarizes the five design steps to help develop the best in front of the ADC
