我们提出了一种新型读出电子学系统，用于大型超导电磁谐振器阵列（如动力学电感探测器（KIDs）），该系统基于射频片上系统（RFSoC）架构。读出系统的每个通道设计用于频分复用，可在512 MHz带宽内的唯一频率上，对放置在单条微波传输线上的多达1024个高品质因数谐振器进行复用。我们描述了数字和模拟信号处理链的设计，用于在Xilinx ZCU111 RFSoC评估板上实现双通道2048谐振器系统，同时结合定制的中频（IF）系统，将RFSoC频段转换为高达4 GHz的更高频率。我们还详细介绍了相关软件接口，该接口提供了一系列常用工具，用于表征KID谐振器以及将其作为测光毫米波成像仪的一部分进行操作。此外，我们还提供了单个读出组件、完整读出系统在隔离状态下以及用于读出KID谐振器时的噪声表征结果。
英文摘要
We present a novel readout electronics system for large arrays of superconducting electromagnetic resonators, such as kinetic inductance detectors (KIDs), based on a Radio Frequency System on Chip (RFSoC) architecture. Each channel in the readout system is designed for frequency division multiplexing of up to 1024 high quality factor resonances placed on a single microwave transmission line at unique frequencies within a 512 MHz bandwidth. We describe the design of the digital and analog signal processing chains for the implementation of a two-channel 2048-resonator system on the Xilinx ZCU111 RFSoC evaluation board in combination with a custom intermediate frequency (IF) system to convert the RFSoC band to higher frequencies up to 4 GHz. We also detail an associated software interface that provides a range of tools commonly utilized for characterizing KID resonators and for operating them as part of a photometric millimeter-wave imager. We additionally provide noise characterizations of the individual readout components, along with the complete readout system in isolation and in operation to readout KID resonators.
