Based on the hardware it is shown that the performance of both register file and latch improves by 2-3.5% per 10/spl deg/C reduction in temperature. The standby power for SOI reduces by 1.5% to 3% per 10/spl deg/C temperature drop down to -30/spl deg/C. The SOI chip is shown to have more significant performance improvement at low temperatures compared to bulk chip due to the floating body effect which partially offsets the increase in the threshold voltages (Vt). The low temperature performance gain is attributed to reduction in capacitance (around 7-8%) and rest is due to dynamic threshold voltages. At -30/spl deg/C the register file is capable of functioning close to 1.02 GHz for read and write operations in a single cycle.","PeriodicalId":188020,"journal":{"name":"ISLPED'00: Proceedings of the 2000 International Symposium on Low Power Electronics and Design (Cat.

This has been the driver for the revolution in communications and computing. However, questions regarding the limits of scaling (and hence Moore's Law) have arisen in recent years due to the emergence of deep submicron noise. This paper describes noise in deep submicron CMOS and its impact on digital as well as analog circuits. In particular, noise-tolerance is proposed as an effective means for achieving energy and performance efficiency in the presence of DSM noise.","PeriodicalId":188020,"journal":{"name":"ISLPED'00: Proceedings of the 2000 International Symposium on Low Power Electronics and Design (Cat.

The proposed approach combines two low-power techniques which utilize supply voltage reduction. The first technique, multiple voltage distribution (MVD), attempts to reduce power consumption by assigning reduced supply voltages to circuit modules while satisfying timing constraints. The second technique, adaptive voltage scaling (AVS), dynamically adjusts these multiple voltages to meet throughput requirements resulting in further power reduction. An FIR filter application using the combined MVD-AVS power management scheme for two adaptively scaled supply voltages is shown to consume one-third the power of a fixed supply voltage scheme, and half the power consumed with a single supply AVS.","PeriodicalId":188020,"journal":{"name":"ISLPED'00: Proceedings of the 2000 International Symposium on Low Power Electronics and Design (Cat.

Due to the characteristics of such an application, the proposed system presents the typical design challenges of low-voltage, low-power circuits. The work demonstrates that, thanks to the narrow bandwidth typical of biological signals (50-150 Hz), oversampling conversion techniques can be advantageous in terms of power dissipation at a given dynamic range. The converter is designed in a 0.8 /spl mu/m CMOS technology using the switched op-amp technique. The /spl Sigma//spl Delta/ converter is a third order modulator with an oversampled frequency of about 8 kHz and the circuit can operate at a minimum supply voltage of 2 V, while dissipating 2 /spl mu/W at most.

This implementation is shown to be superior in respect of power consumption compared to an equivalent implementation with a high-speed A/D converter in the front-end, to execute signal processing tasks that include decimation. The power savings are only due to relaxed requirement on A/D conversion rate, as a direct consequence of the decimation.
