To enable extremely long-term ambulatory monitoring, several power saving techniques are proposed, including global cognitive clocking, pseudo-downsampling wavelet transform, adaptive storing, and denoising-based run-length compression. An on-chip low-complexity cardiac signal analysis module is proposed to realize comprehensive analysis functions. Near-threshold circuit technique is applied to the overall system. Implemented in 0.18 μm CMOS, the proposed cognitive ECG processor consumes only 457 nW at 0.5 V supply for real-time ambulatory monitoring. Compared with existing designs, the presented ECG processor achieves the lowest power consumption.","PeriodicalId":296544,"journal":{"name":"2013 IEEE Asian Solid-State Circuits Conference (A-SSCC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127113280","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}

To increase the communication distance for indoor applications, the output power of transmitters should be increased. However, it has been difficult to simultaneously realize high power efficiency together with low power consumption and the wideband required for 10Gbps communication in the power amplifiers used in transmitters. To realize 10Gbps communication for indoor applications with CMOS technology, the co-design of a modulator with low impedance variation and a wideband power amplifier is proposed by adopting amplitude-shift keying. The proposed transceiver is fabricated using a 40nm CMOS process, and is the first transceiver to realize 11Gbps with a communication distance of 3m and has a power consumption of 208.9mW. The transmitter realized maximum 2.8dBm output power with 77mW power consumption using a power amplifier with a 3dB bandwidth of 18GHz.","PeriodicalId":296544,"journal":{"name":"2013 IEEE Asian Solid-State Circuits Conference (A-SSCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115098161","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 proposed PIDLL utilizes a new phase inversion scheme to reduce the total number of delay elements (DEs) in the digitally controlled delay line (DCDL) by approximately one-half, enabling shorter locking times, lower power consumption, reduced jitter performance, and a smaller area, while maintaining a wide operating frequency range. To achieve high delay resolution and linear delay characteristics, a three-stage DCDL using a new area-efficient digital feedback delay element (FDE) is proposed. The FDE is also utilized to implement a new DCC that obtains a duty-cycle error of less than ±0.85% over a 30-70% input duty-cycle range. The proposed DCC-equipped PIDLL is implemented in a 0.13-μm CMOS process, occupies an area of 0.11 mm2, and operates over a wide frequency range of 0.1-1.5 GHz.

Several techniques are used to enhance co-existence performance of Bluetooth with cellular and Wi-Fi. First is the design of current-mode interfaces from LNA to complex BPF for better linearity and the additional antialiasing LPF placed before ADC for outband rejection in the RX. Second is the use of a passive voltage sampling mixer to lower out-of-band emission noise floor in TX. Moreover, only two inductors are used, one of which is a field-cancelling inductor used in VCO layout to achieve a spur-free LO signal, minimizing magnetic coupling from other parts of SoC. The TX output power is +11dBm at BDR mode and +8dBm at EDR3 mode, with 1.5-kHz frequency drift and <;6% RMS DEVM. The RX sensitivity is better than -96.5dBm and -89.2dBm for BDR and EDR3 modes respectively.

The emergence of many-core computing as the next step in the progression of the industry presents several design challenges for system architects: reasonable power consumption, software programming, core reliability, and core utilization for scalable performance.
