This paper presents design and preliminary performance of a mixed-signal front-end electronics dedicated to CZT detectors. It is implemented by a full-customized readout application-specific integrated circuit (ASIC) with a post digital pulse shaping algorithm in FPGA. In this scheme, the analog front-end consists of a preamplifier using split-let topology followed by a variable gain amplifier. A...
The emergence of multi-electrode array enables the study of real-time neurophysiological activities across multiple regions of the brain. However, the real-time extracellular action potentials recorded on any electrode represent the simultaneous electrical activity of an unknown number of neurons which present a critical challenge to the accuracy of interpretation and identification of the neural...
This is a brief review of recent work on the prospective hybrid CMOS/memristor circuits. Such hybrids combine the flexibility, reliability and high functionality of the CMOS subsystem with very high density of nanoscale thin film resistance switching devices operating on different physical principles. Simulation and initial experimental results demonstrate that performance of CMOS/memristor circuits...
Design productivity of MPSoC is a major challenge for semiconductor industry. Low design productivity affects concurrent engineering on increasingly software dominated SoC design. In this paper we describe automatic design methodologies for MPSOC and prototyping on multi-FPGA platforms which allows fast design productivity. Case studies of actual implementation for both homogeneous and heterogeneous...
We have employed bulk acoustic wave and surface acoustic wave devices for the sensitive and specific detection of biological agents in complex liquid media. We have produced a robotic liquid delivery system coupled to a multi-layer microfluidic manifold that delivers liquids in a controlled manner to pairs of resonant acoustic sensors in a dasiaUSBpsila type docking station. These resonators were...
