The importance of an interconnect pattern density model in ASIC design flow for a 90nm technology is presented. It is shown that performing the timing analysis at the worst-case corner model for interconnect variation, without the knowledge of interconnect pattern density, often results in overdesign. Our experiments on real ASIC products indicate that knowledge of interconnect pattern density ...

The design and performance of a Next Generation Sampling Comparator Probe (NGSCP) is described. It is intended as one of a group of probes designed for use with the NIST Sampling Waveform Analyzer (SWA). The probe design is centered on an application specific integrated circuit (ASIC) analog comparator featuring a bandwidth of 6 GHz. The design considerations of the ASIC analog comparator and t...

This paper describes the combination of educating both, hardware and software with one practical lab. The needs to offer such a co-training concept are brought out by the demands of industry towards the desired skills of today’s engineers. An engineer’s view must no longer be restricted to his/her own work, but has to be widened to a complete system view. To provide an appropriate education sch...

Turbo decoding is viewed as superior alternate decoding technique in communication system, the circuit complexity and power consumption of turbo decoder implementation can often be prohibitive for power constrained system. To address these issues a power efficient turbo decoder based on soft out viterbi algorithm is designed. SOVA based turbo decoder can be implemented with high throughput and ...

Cut-Through switching techniques, and Application Spec@ic Integrated Circuit (ASIC)-based wire-speed routing both attempt to improve network pe~ormance whenever possible. While switching advocates prefer the, “Route once, switch thereafter” approach, ASIC-based routing vendors believe the “Route wherever you wish” approach is the prevailing long-term solution. Both attempt to eliminate the cost...

The charge sharing effect in pixelated CdZnTe (CZT) detectors with a common anode steering grid has been studied. The impact on energy resolution of weighting potential cross-talk and ballistic deficit due to cathode signal shaping has been investigated. A detailed system modeling package considering charge induction, electronic noise, pulse shaping, and ASIC triggering procedures has been deve...

The adaptive successive interference canceler (ASIC) is a multistage receiver that sequentially detects and removes cochannel users from the received signal impinging on a single antenna element. Each stage of the ASIC consists of a conventional matched filter (MF) detector and an adaptive interference canceler (AIC) that employs the least-mean-square (LMS) algorithm to recursively estimate the...

Tissue acidosis is an important feature of inflammation. It is a direct cause of pain and hyperalgesia. Protons activate sensory neurons mainly through acid-sensing ion channels (ASICs) and the subsequent membrane depolarization that leads to action potential generation. We had previously shown that ASIC transcript levels were increased in inflammatory conditions in vivo. We have now found that...
