First, we propose a closed-loop architecture utilizing three techniques to achieve the 1st tap stage design, namely a merged latch and summer, reduced latch gain, and a dynamic latch design. Then, we suggest to merge the feedback MUX with the tap differential pairs within clock-control summers array (CCSA) to accomplish the 2nd and 3rd tap stages design. The total power consumption of the 3-tap DFE is 27mW under 1V, achieving 0.67 pJ/bit energy efficiency.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130605283","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}

Designed in a 130 nm BiCMOS technology, the proposed structure explores ground plane switching to perform impedance tuning. It exhibits a 16 Ohms shift over characteristic impedance - equivalent to 30% of tuning range - with a Q-factor higher than 16 thanks to a shielding used in slow-waves transmission lines. Using this topology versus a classical 50 Ohms coplanar waveguide into a reconfigurable pi-type matching network with tunable stubs, it allows to cover around 100% more of impedances in the Smith Chart with a “2 dimensional” tuning.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129741560","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 miniaturization of the MEAs goes with an increase of the electrodes impedance and necessitates high input impedance neural amplifiers; otherwise it results in a significant loss of signal and low SNR. The circuit presented here is designed on a 0.35 μm CMOS technology. Two versions are described which capacitive input impedance is 1 pF. One is robust to high input offset and consumes 13.5 μA; the other one is more sensitive to offset but consumes only 3.7 μA. Both generate less than 7 μVRMS input-referred noise and their NEF figures are respectively 8.4 and 3.66. These features are competitive in view of the literature on neural amplifiers, while the circuit was specifically designed to present a high input impedance.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130211507","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 chip includes an RF-DC rectifier, low power analog to digital converter (ADC) and a resistor emulation circuit (REC).

Prediction of the nonlinear behavior of passive circuits like mixers, attenuators or switches play an important role in low-distortion designs, but also causes trouble due to the inability of threshold voltage based compact models to inherently model higher order nonlinearities around zero drain-source voltage. This paper introduces a systematic workaround enabling the designer to receive qualitative higher order simulation data around that important operating point when there is no access to one of the advanced surface potential or inversion charge based transistor models.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133189050","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}

For example, recent neural models defined by neuro-scientists exhibit interesting properties for an execution in embedded and autonomous systems: distributed computing, unsupervised learning, self-adaptation, self-organisation, tolerance. But these properties only emerge from large scale and fully connected neural maps that result in intensive computation coupled with high synaptic communications. We are interested in deploying these powerful models in the embedded context of an autonomous bio-inspired robot learning its environment in realtime. So we study in this paper in what extent these complex models can be simplified and deployed in hardware accelerators compatible with an embedded integration. Thus we propose a Neural Processing Unit designed as a programmable accelerator implementing recent equations close to self-organizing maps and neural fields. The proposed architecture is validated on FPGA devices and compared to state of the art solutions. The trade-off proposed by this dedicated but programmable neural processing unit allows to achieve significant improvements and makes our architecture adapted to many embedded systems.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132519234","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}

A RZ DAC is utilized to realize a fast compensation path from the quantizer output to the input of the last integrator. After proper tuning of the scaling coefficients, the original NTF of the modulator can be restored, which has been verified in a 3rd order, single-bit single-loop CT ΔΣ modulator. By using the modified compensation technique, the GBW requirements on the amplifiers can be relaxed significantly while maintaining the SQNR performance and the modulator stability.

In this paper we propose a new approach in autofocus systems design that uses some linear control theory results that allow to obtain the optimal feedback gain in the sense of quadratic sharpness hypothesis. The method proposed in this work allows to improve the existent autofocus systems that are based on the sharpness autofocus using the optimal feedback gain.
