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.

这个小型企业创新研究第二阶段项目将展示一种包含闪存模数转换器(ADC)和高级触发电路的自触发式瞬时数字转换器芯片。将改进第一阶段期间设计的自触发电路，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次信号能够被捕获。在第一阶段开始的高级比较器工作将在第二阶段完成，以产生一个精度低于皮秒的纠错比较器。由此产生的自触发瞬时数字转换器芯片将能够通过信号本身或外部提供的触发脉冲来触发。这种对我们以前的瞬时数字转换器芯片的推广，以及在其他程序下开发的高级体系结构，将以大于10 GHz的输入带宽和高达20 GSA/S的采样速率运行。泰克SCD-5000瞬时数字转换器提供了基于模数转换器的任何数字转换器中最高的带宽和性能。这种产品从市场上下架提供了一个重要的商机。来自国家点火设备和布鲁克海文国家实验室相对论重离子加速器的潜在客户已经表达了对我们潜在产品的兴趣。
