A two-step transition inverter raises the VT conversion gain to 100ps/V which is >10× higher than a conventional current-starved inverter. The number of required inverter stages is reduced to 4 from 64, resulting in 1/8 conversion latency and thus 13.2dB THD suppression at 500MHz full Nyquist. A test-chip measurement successfully demonstrates -52.5dB THD at 500MHz without sampling-and-hold. Effective VT conversion linearity is measured to be 1ps/LSB with INL/DNL of less than +/-0.53LSB. The proposed VTC consumes 84μm2 silicon area and 0.18mW at 1GS/s.","PeriodicalId":246471,"journal":{"name":"ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127884385","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}

Removing blur requires deconvolving the blurred image with a kernel which is typically unknown and needs to be estimated from the blurred image. This kernel estimation is computationally intensive and takes several minutes on a CPU which makes it unsuitable for mobile devices. This work presents the first hardware accelerator for kernel estimation for image deblurring applications. Our approach, using a multi-resolution IRLS deconvolution engine with DFT based matrix multiplication, a high-throughput image correlator and a high-speed selective update based gradient projection solver, achieves a 78× reduction in kernel estimation runtime, and a 56× reduction in total deblurring time for a 1920×1080 image enabling quick feedback to the user. Configurability in kernel size and number of iterations gives up to 10× energy scalability, allowing the system to trade-off runtime with image quality. The test chip, fabricated in 40 nm CMOS, consumes 105 mJ for kernel estimation running at 83 MHz and 0.9 V, making it suitable for integration into mobile devices.","PeriodicalId":246471,"journal":{"name":"ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130453419","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}

Owing to their broadband amplification capabilities, reflection-type amplifiers based on negative differential resistance (NDR) devices provide means to overcome these limitations. Herein, we propose a novel reflection amplifier circuit consisting of three graphene FETs (GFETs) which leverages its unique NDR characteristics. We show through rigorous simulation and modeling that broadband amplification exceeding several hundreds of GHz should be possible for the scaled graphene circuit. In addition, both the gain and frequency of operation can be highly modulated by varying the bias in the NDR region. Finally, we provide an experimental evidence of reflection amplification in the proposed circuit.","PeriodicalId":246471,"journal":{"name":"ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133851696","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}
