The proposed SA-ADC uses a supply voltage of 1 V instead of 2 V for a 2 V input voltage range in order to reduce power consumption. The proposed ADC reduces the conversion time and area by sampling the input signal only twice and converting it to the most significant bit (MSB) and lower 10-bit without any additional analog circuit. A test chip with the proposed SA-ADC was fabricated using a 0.18 μm CMOS process technology. The measurement results show that the total power consumption of the proposed SA-ADC is 9.0 μW. The static and dynamic power consumptions using a 1 V supply voltage are reduced by 54% and 76%, respectively, compared with those using a 2 V supply voltage. In addition, the proposed SA-ADC achieves a short conversion time of 6.5 μs and occupies a small area of 320 μm × 270 μm.

With aids of binaural cues and minima controlled recursive average (MCRA) approach, the proposed NR algorithm consists of a directional mask and an estimated mask. The directional mask exploits the interaural time difference (ITD) together with the interaural level difference (ILD) of two input sources to attenuate the lateral noise, while the estimated mask is used to further reduce the background noise and the coherence noise. Investigated by the circumstances with the −3 dB, 0 dB, and 3 dB, respectively, cocktail-party effect, the simulation results show that the proposed binaural NR algorithm gains an average of approximately 5.07 dB SNR improvement. Moreover, the speech intelligibility index (SII) performance is superior, comparing that with the state-of-the-art NR algorithms for hearing aids. The proposed binaural NR algorithm has been implemented in TSMC 90 nm CMOS high-VT technology. The chip design is operated by 288 KHz and consumes approximately 121.6 μW (@1 V). The chip design can be operated by 0.6 V for real-time processing 24 kHz audio. The simulated power consumption is approximately 64.52 μW for binaural hearing aids.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"28 1","pages":"21-24"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75722434","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}

Besides, the proposed filter can be configured as both single-ended and differential forms. Circuit simulation using 0.35-μm CMOS process shows that, to obtain a 100-Hz cutoff frequency with a 52.2-dB dynamic range, total capacitance of 36 pF and power consumption of 0.36 nW are required for the differential filter that operates in subthreshold region from a supply voltage of 0.6 V.

The proposed architecture employs multi-tone signaling to reduce inter-symbol interference (ISI) and to increase receiver (RX) timing margin. A single-sideband (SSB) modulation has also been employed for saving of required bandwidth per sub-channel, so as to minimize inter-channel interference (ICI). System-level simulation results show that the proposed TRX can easily transmit 20 Gb/s data stream over a lossy backplane channel that exhibits 28-dB attenuation at 10 GHz while requiring neither of continuous-time linear equalizer (CTLE) and decision feedback equalizer (DFE). By transmitting 3-to-5 Gb/s data stream over each of four sub-channels, at least 44% unit interval (UI) eye openings are achieved for all sub-channels when 20 Gb/s aggregate data is transmitted.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"4 1","pages":"164-167"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76355607","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}

However, these cameras often produce regions with missing pixels. The missing pixel regions, which refer to holes, will not contain any depth information for the depth image. This reason would lead the performance to degrade seriously in modern-day three-dimensional (3D) video applications. Therefore, how to effectively utilize image information and depth maps become more and more important. In this paper, we propose adaptive texture-similarity-based hole filling (ATSHF) and adaptive texture-similarity-based depth enhancement (ATSDE). The proposed system, which is used for the enhancement of depth maps, is achieved by suppressing the noise, filling holes and sharpening object edges simultaneously. Experimental results demonstrate that the proposed method provides a superior performance, especially around the object boundary. Beside, we compare with the other state-of-the-art methods about the image and the depth map enhancement.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"33 1","pages":"192-195"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91105623","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}

Our compact Verilog-A model includes all the short channel effect as well as the geometrical dependent parasitics, which are crucial for short channel devices. The model is well calibrated with TCAD and reported fabricated data. The standard cell library developed comprise INVERTER, NAND, and NOR gate cells. Finally, we compared the standard cell performance to FinFET based standard cell.
