提出了一种具有片上内建自测试(BIST)功能的相控阵接收机结构。在BIST路径中使用对称布局信号分配器来消除由无源电路的不对称性引起的检测误差。通过用屏蔽电路结构紧凑地构成信号分配器，抑制了对主接收电路的不利影响。我们测试了一款28 GHz的cmos相控阵接收器芯片。利用该芯片的接收机内建自测试功能，验证了相控阵接收机阵元之间的相位特性差异是可以确定的。
We propose a configuration of a phased-array receiver with an on-chip built-in self-test (BIST) function. Detection errors caused by asymmetry of the passive circuit are eliminated using a symmetrical layout signal distributor in the BIST path. By composing the signal distributor in compact manner with a shielded circuit structure, the adverse effect on the main receiving circuit is suppressed. We tested a 28-GHz CMOS phased-array receiver chip. Using this chip's receiver BIST function, we demonstrated that the difference in characteristics of phase between array elements in a phased-array receiver can be ascertained.
