SBIR Phase II: A Self-Triggered Pulse Acquisition System with Greater than 10 GHz Bandwidth

这个小企业创新研究第二阶段项目将演示一种自触发瞬态数字化仪芯片，该芯片包含一个闪存模数转换器（ADC）和先进的触发电路。在第一阶段设计的自触发电路将得到改进，以便可以施加任意延迟。这将使在触发点之前发生的部分单发信号能够被捕获。在第一阶段开始的高级比较器工作将在第二阶段完成，以产生亚皮秒精度的误差校正比较器。由此产生的自触发瞬态数字化芯片将能够由信号本身或外部提供的触发脉冲触发。这种对我们以前的瞬态数字化芯片的推广，加上在其他项目下开发的先进架构，将在大于10 GHz的输入带宽下工作，采样率高达20 GSa/s。泰克SCD-5000瞬态数字化仪提供了基于模数转换器的最高带宽和性能。这种产品从市场上撤下提供了一个重要的商业机会。来自布鲁克海文国家实验室的国家点火装置和相对论重离子加速器的潜在客户对我们的潜在产品表示了兴趣。

This Small Business Innovation Research Phase II project will result in a demonstration of a self-triggered transient digitizer chip containing a flash analog-to-digital converter (ADC) and advanced triggering circuits. The self-triggering circuit designed during Phase I will be improved such that an arbitrary delay can be imposed. This will enable parts of single-shot signals occurring before the triggering point to be captured. The advanced comparator work begun in Phase I will be completed in Phase II to result in anerror-correcting comparator with sub-picosecond accuracy. The resulting self-triggering transient digitizer chip will be able to trigger either by the signal itself, or an externally supplied trigger pulse. This generalization of our previous transient digitizer chip, together with the advanced architecture developed under other programs, will operate with greater than 10 GHz input bandwidth, and at a sampling rate of up to 20 GSa/s.The Tektronix SCD-5000 transient digitizer provided the highest bandwidth and performance of any digitizer based on an analog-to-digital converter. The removal of this product from the market provides a significant business opportunity. Potential customers from the National Ignition Facility and the Relativistic Heavy Ion Accelerator at Brookhaven National Laboratory have expressed interest in our potential product.
