On-the-fly Computation Method in Field-Programmable Gate Array for Analog-to-Digital Converter Linearity Testing

High-Resolution Time-to-Digital Converter in Field Programmable Gate Array

Two high-resolution time-interval measuring systems implemented in a SRAM-based FPGA device are presented. The two methods ought to be used for time interpolation within the system clock cycle. We designed and built a PCB hosting a Virtex-5 Xilinx FPGA. We exploited high stability oscillators to test the two different architectures. In the first method, dedicated carry lines are used to perform...

signal specific successive approximation analog to digital converter

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Analog-to-Digital Converter Testing

Analog-to-digital converters are essential building blocks in modern electronic systems. They form the critical link between front-end analog transducers and back-end digital computers that can efficiently implement a wide variety of signal-processing functions. The wide variety of digitalsignal-processing applications leads to the availability of a wide variety of analog-to-digital (A/D) conve...

A Floating-Gate-Based Field-Programmable Array of Analog and Digital Devices

A hybrid, mixed-signal, reconfigurable system, based on the combination of a field-programmable analog array (FPAA) and FPGA is presented. The chip is a fine-grained interleaving of interchangeable analog and digital tiles, wherein a tile comprises either analog or digital computational elements and interconnect. The chip comprises the array core, high-speed I/O, and floating-gate programming i...
