With the recent trends in wireless communication technology, the inherent problems associated with the past radio receivers are now being exterminated by the use of its digital counterparts. In the past radio receivers were designed with analog circuitry. This inherently has the same problems that all analog circuits have, overcoming this disadvantages the Two Channel Digital receiver is used for...
This paper describes an ATE extension module that enables a low-cost test system to be applied to advanced (multi-GHz) memories. The target application is for testing memories with data rates above 3.2Gbps. The test module uses state-of-the-art FPGAs for economical autonomous pattern synthesis and comparison under the high-level supervision of a low-cost “host” test platform (ATE). The FPGA logic...
In this paper, Signal integrity (SI) analysis is used to analyze effect of crosstalk on performance of a High Speed Digital Module: its most critical part is simulated by ADS, a simulation tool, and then it is measured by an oscilloscope to verify the correctness of results. Technology trends toward higher speed and device density have increased complexity of PCB design to support fast varying and...
This article presents a generic digital control system for the stabilization of Radio Frequency (RF) fields used in particle accelerators, the Libera LLRF. Low Level RF (LLRF) systems have an important contribution in the overall performance of the accelerator since they are responsible for the control of amplitude and phase of electromagnetic fields inside the accelerating structures. The goal was...
Access to the pre-beamform data of each array channel on an ultrasound scanner is important to experimental investigations on advanced imaging research topics like adaptive beamforming and synthetic aperture imaging. Through such data access, we can obtain in-vitro or in-vivo insights on various imaging methods without resorting to hardware implementation. This paper reports the development of a pre-beamform...
