A serial power (SP) scheme will be used for the ITk Pixel Detector. New elements are required to operate and monitor a serially powered detector, including a Detector Control System (DCS), constant current sources and front-end electronics with shunt regulators. A demonstrator for the three outer barrel layers of the ITk Pixel Detector is being built at CERN to verify and qualify the SP concept, and to gain experience operating a SP chain. It includes all required elements for controlling and operating SP chains safely, from an interlock system to in-situ monitoring with a new DCS. A first full electrical prototype with seven quad modules was successfully tested. This prototype includes pixel modules, the DCS elements, realistic services and can be read out by different data acquisition systems. Problems identified during the commissioning and operation of the small electrical prototype went into the requirements for the future front-end (FE) chips. Many institutes worked on the development and integration of the individual parts. Further and longer chains are under construction and will allow tests of multiple SP chains mounted on the same local support in parallel. It is also foreseen to operate a SP chain with 16 modules.","PeriodicalId":400748,"journal":{"name":"Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2018)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128728371","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}

The processing of these trigger primitives (TPs) is performed by dedicated trigger concentrator cards (TCCs) located in the CMS service cavern. Updates to the functionality of the TCCs were required to respond to the challenging experimental conditions of LHC Run 2, where the center-of-mass of proton-proton collision energy was 13 TeV and the peak instantaneous luminosity of the proton beams reached 2x1034 cm-2 s-1. A new algorithm, termed the Cumulative Overflow Killing Engine (COKE), has been developed and implemented via software and firmware updates to the TCCs in order to automatically detect and mask noisy or problematic TPs via configurable thresholds. The autorecovery of the TCCs has also been improved, to manage the Single Event Upsets (SEUs) from the front-end electronics. This allows the detector to trigger efficiently without direct expert intervention, and the thresholds can evolve with evolving LHC conditions.

It is well documented that certain 130-nm CMOS technologies exhibit an increase in the leakage current when exposed to ionising radiation. Such 130-nm technology is employed in the readout ASICs of the ATLAS ITk Strip Tracker Upgrade. Using the so-called ABC130 prototype chipset, measurements are presented which allow the parametrisation of the increase in current as a function of dose rate in the region of phase space most applicable to High-Luminosity LHC conditions. Studies investigating the batch-by-batch, chip-by-chip and wafer-by-wafer variation of the total current increase are presented which demonstrate a significant batch-by-batch variation alongside non-negligible variations within wafers. Furthermore, studies are shown investigating the long-term annealing of irradiated chips (up to four months storing chips at 80 C). Finally, the feasibility of pre-irradiating wafers to mitigate the current increase is demonstrated.","PeriodicalId":400748,"journal":{"name":"Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2018)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115313238","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}

SAR ADC demands precise internal digital to analog converter (DAC). To save power, the DAC is mainly implemented using capacitors (CDAC). Its precision depends mostly on layout implementation which must minimize the various parasitic effects. This paper presents two new layout design approaches of CDAC for SAR ADC used in a pixel detector implemented in 180 nm SOI technology. The various types, topology, size of the capacitors, power consumption, layout area, speed, and any nonlinearities are discussed. First is a new layout design of the 10-bit split capacitor DAC with \u0000Metal-Insulator-Metal capacitors, and, the second, is a 8-bit binary-weighted DAC with Metal-Oxide-Metal capacitors. The new layout of the metal-oxide-metal capacitor topology provides better accuracy of the DAC. The layout styles for each of CDAC, with low parasitic capacitances, are shown. The post layout simulations confirm that both capacitor arrays have an integral, differential nonlinearity, less than one least significant bit without a calibration scheme.","PeriodicalId":400748,"journal":{"name":"Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2018)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125661442","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}
