论文摘要
数十年来，高能量物理（HEP）仪器一直集中在电离辐射的探测器上 - 在这种情况下，入射颗粒或光子的能量足以在气体，液体或固体物质中创建移动电荷，可以通过前端电子设备（费用）处理有关事件辐射的位置，能量和时机的信息。然而，最近所提供的HEP实验需要在不可用的电离检测器的射频（RF）范围内感知或控制EM辐射。这些实验可以利用由商业部门无线数据通信的爆炸性增长促进的新兴微电学发展。 摩尔的法律在半导体技术方面的进步带来了最新的高级微电子组件的发展，并具有开创性的模拟数字整合和处理速度。特别是，RF“芯片系统”（RFSOC）平台为模拟世界（ADC和DACS）提供了多个数据转换器接口，具有带宽接近10GHz的带宽，并在同一硅模具上提供了大量的数字信号处理资源。此类设备消除了长期以来用来将离散ADC和DAC与FPGA处理器搭配的复杂PC板接口，从而从根本上降低了功耗，阻抗不匹配和足迹区域，同时允许消除模拟预处理电路以支持数字处理。这些设备用于广泛部署，有助于加速在几个大批量商业市场中“软件定义的无线电”趋势。在此白皮书中，我们突出显示了一些HEP应用程序，其中领先的RF微电子可以成为关键推动器。
For many decades High Energy Physics (HEP) instrumentation has been concentrated on detectors of ionizing radiation -- where the energy of incident particles or photons is sufficient to create mobile charge in gas, liquid, or solid material, which can be processed by front end electronics (FEE) to provide information about the position, energy, and timing of the incident radiation. However, recently-proposed HEP experiments need to sense or control EM radiation in the radiofrequency (RF) range, where ionization detectors are unavailable. These experiments can take advantage of emerging microelectronics developments fostered by the explosive growth of wireless data communications in the commercial sector. Moore's Law advances in semiconductor technology have brought about the recent development of advanced microelectronic components with groundbreaking levels of analog-digital integration and processing speed. In particular, RF "System-on-Chip" (RFSoC) platforms offer multiple data converter interfaces to the analog world (ADCs and DACs) having bandwidths approaching 10GHz and abundant digital signal processing resources on the same silicon die. Such devices eliminate the complex PC board interfaces that have long been used to couple discrete ADCs and DACs to FPGA processors, thus radically reducing power consumption, impedance mismatch, and footprint area, while allowing analog preconditioning circuits to be eliminated in favor of digital processing. Costed for wide deployment, these devices are helping to accelerate the trend towards "software defined radio" in several high-volume commercial markets. In this whitepaper we highlight some HEP applications where leading-edge RF microelectronics can be a key enabler.
