The proposed model exploits the sampled nature of the PLL where most of its analog behavior takes effect during the phase detection, and remains almost constant during the rest of the reference cycle. The PLL model simulation run time takes only 1 second, which makes it a perfect fit for pre-silicon digital validation as well as top-down design methodology. Compared to transistor-level Spice simulations, the proposed model shows a correlation of more than 97% for the PLL locking behavior, jitter, and phase noise. The PLL model is used to exercise critical features like spread-spectrum clocking (SSC) and adaptive frequency system (AFS). In addition, the model was integrated in a pre-silicon validation environment and enabled catching design bugs.","PeriodicalId":6665,"journal":{"name":"2015 IEEE Custom Integrated Circuits Conference (CICC)","volume":"28 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77973082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a huge volume of literature on this topic as implementation of III-V monolithic integration with Si has been the holy grail for last four decades; targeting a wide range of applications including RF devices, LEDs, lasers, photo-detectors and the like. The key drivers have been the cost reduction, scalability with Si wafer diameter, and accessibility to highly scaled integrated circuits next to III-V devices. With the current focus on CMOS the pace of progress on monolithic integration has accelerated by leaps and bounds partly because of its vast impact on CMOS scaling, and partly due to the aggressive CMOS roadmap requirements. The discussion below concentrates on In0.53Ga0.47As channel which is the dominant III-V material being pursued for future technology. Despite the narrow focus, fundamental and engineering challenges posed by this material encompass a broad range of material topics including epitaxial growth, crystallographic defects and their dynamics during growth and subsequent processing, clever device architecture to alleviate adverse impact of defects on device leakage, and innovative engineering for material improvement.","PeriodicalId":6665,"journal":{"name":"2015 IEEE Custom Integrated Circuits Conference (CICC)","volume":"22 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73180986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While conjugate matching gives optimal efficiency for lossless passives, the results are markedly different when constituent passives have finite quality factors. Given the load and source impedances, there may be infinite ways to achieve the transformation, albeit each incurring different loss. In this paper, we investigate the methods to deduce the global maximum efficiency of power transfer between two arbitrary impedances with lossy passives. This paper also proposes methods to combine this with nonlinear load-pull simulations for optimal efficiency combiner and matching network for integrated PAs.

The approach results in a significant reduction in power, leakage, area and wire-length, without sacrificing performance of the design. At the heart of this approach is a configurable threshold logic gate. Using a standard cell library of such gates, a new technology mapping algorithm is applied to automatically transform a given netlist into one with an optimal mixture of conventional logic gates and threshold gates. The mapping algorithm is based on logic decomposition of Boolean functions into specific threshold functions. This approach was used to fabricate a 32-bit signed 2-stage Wallace-Tree multiplier in a 65-nm LP technology. Simulation and chip measurement results of the multiplier show a 33% improvement in dynamic power at 30% switching activity, 24% lower core area, 45% lower wire-length and 50% lower leakage without any performance degradation, compared to a functionally equivalent, conventional standard cell implementation. Similar results are shown for a FIR filter, a 32-bit MIPS, a 128-bit AES encryption circuit and a floating-point multiplier.","PeriodicalId":6665,"journal":{"name":"2015 IEEE Custom Integrated Circuits Conference (CICC)","volume":"6 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88807993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
