It is composed of a matrix of 48 × 64 pixels with a 4-bit column-parallel analog-to-digital converter (ADC). The pixel concept combines in-pixel amplification with a correlated double sampling (CDS) operation in order to reduce the temporal and fixed pattern noise (FPN). The self-triggered ADC accommodating the pixel readout in a rolling shutter mode completes the conversion by performing a multi-bit/step approximation. The ADC design was optimized for power saving at sampling frequency. Accounting the fact that in the outer layers of the ILC vertex detector the hit density is in the order of a few per thousand, this ADC works in two modes: active mode and inactive mode. The average energy and total capacitance are significantly reduced by a power-gating control and a switching network, respectively. The prototype sensor was fabricated in a 0.35 μm CMOS process with a pixel pitch of 35 μm. The designed 4-bit ADC dissipates, at a 3-V supply and 6.25-MS/s sampling rate, 486 μW in its inactive mode, which is by far the most frequent. This value rises to 714 μW in case of the active mode. Its footprint amounts to 35 × 545 μm2.","PeriodicalId":269365,"journal":{"name":"2012 19th IEEE International Conference on Electronics, Circuits, and Systems (ICECS 2012)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133919627","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}

This paper presents a new algorithm for motion estimation focused on high definition videos named Multiple Iterative Random Search (MIRS). This algorithm uses randomness and multiple iterative steps as strategy to avoid local minima falls, achieving better quality results than traditional fast algorithms. MIRS is a hardware friendly algorithm since it has five iterative steps which did not have data dependencies, then these five iterative steps can be implemented in parallel, reaching a processing rate similar to other fast algorithms. That characteristic becomes MIRS a very competitive option for hardware implementation, since it is possible to reach very high processing rates with very good quality results. The comparative results show that MIRS algorithm presented the best PSNR among all evaluated fast algorithms. MIRS is also able to reduce in 70 times the number of evaluated blocks when compared with Full Search algorithm with a PSNR drop of only 0.71dB.","PeriodicalId":269365,"journal":{"name":"2012 19th IEEE International Conference on Electronics, Circuits, and Systems (ICECS 2012)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134274118","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}
