论文摘要
随着我们的世界数字化,电子系统变得越来越无处不在。同时,即使是基本组成部分,每年都会通过全球数百个研发组设计新的晶体管,备忘录,电压/当前参考,数据转换器等,从而经历了一波改进。迄今为止,用于测试所有这些设计的主力是一套实验室仪器,包括示波器和信号发电机,以提及最受欢迎。但是,随着组件变得越来越复杂,PIN数字飙升,对更平行和多功能测试工具的需求也变得更加紧迫。在这项工作中,我们描述并基准了一个FPGA系统,该系统开发了解决这一需求。该通用测试系统具有64通道源表单元(SMU),而数字I/O的32个数字引脚的银行为2倍。我们证明,此基准系统可以获得$ 170 pa $当前的噪声底,$ 40 ns $脉冲交付$ \ pm13.5 V $和$ 12 ma $最大电流驱动器/频道。然后,我们展示了该仪器在执行三个特征测量任务的选择中的用途:a)二极管和晶体管的电流 - 电压(iv)表征,b)在DAC上对NEMBRSTOR跨BAR阵列的完全平行读取和c)整体非线性(INL)测试。这项工作介绍了一个仪器中包装的下尺度的电子实验室,该实验室为新兴的电子技术提供了更便宜,可靠,紧凑和多功能仪器的转变。
Electronic systems are becoming more and more ubiquitous as our world digitises. Simultaneously, even basic components are experiencing a wave of improvements with new transistors, memristors, voltage/current references, data converters, etc, being designed every year by hundreds of R&D groups world-wide. To date, the workhorse for testing all these designs has been a suite of lab instruments including oscilloscopes and signal generators, to mention the most popular. However, as components become more complex and pin numbers soar, the need for more parallel and versatile testing tools also becomes more pressing. In this work, we describe and benchmark an FPGA system developed that addresses this need. This general purpose testing system features a 64-channel source-meter unit (SMU), and 2x banks of 32 digital pins for digital I/O. We demonstrate that this bench-top system can obtain $170 pA$ current noise floor, $40 ns$ pulse delivery at $\pm13.5 V$ and $12 mA$ maximum current drive/channel. We then showcase the instrument's use in performing a selection of three characteristic measurement tasks: a) current-voltage (IV) characterisation of a diode and a transistor, b) fully parallel read-out of a memristor crossbar array and c) an integral non-linearity (INL) test on a DAC. This work introduces a down-scaled electronics laboratory packaged in a single instrument which provides a shift towards more affordable, reliable, compact and multi-functional instrumentation for emerging electronic technologies.
