The proposed demodulator does not require a post-detection filter to suppress sum-frequency components, and hence is suitable for a low-IF receiver architecture. Applied to a Bluetooth receiver with 500 kHz low-IF frequency, the demodulator reaches 10/sup -3/ BER for 16.5 dB SNR and 1 Mbps data-rate. Small modulation indices between 0.28 to 0.35 are demonstrated. Using a 0.25-/spl mu/m mixed-signal CMOS process, the demodulator occupies an active area of 0.22 mm/sup 2/. The power consumption is 5 mW from a 2.5 V single supply.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.

A low power FIR filter design technique using dynamic reduced signal representation 采用动态降阶信号表示的低功耗FIR滤波器设计技术

Such switching is undesirable in low power applications. In this work, we exploit the sign-extension property of a 2's complement number and propose a reduced representation of 2's complement numbers to avoid sign-extension. Instead of having the high switching activity at the MSB side of the datapath, the proposed number representation avoids switching of the MSBs altogether, and therefore reduces the power dissipation in digital arithmetic circuits. With the proposed technique, the maximum magnitude of a 2's complement number is detected and a reduced representation is dynamically generated to represent the signal. There is a constant error introduced by the reduced representation and such error is compensated accordingly. The proposed signal representation is particularly useful in digital filters where the coefficients are slowly varying and have small magnitudes. Our experimental results have shown a 38% power saving using the proposed technique.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.

Thermally stable ultra-thin Zr silicate for CMOS applications 用于CMOS应用的热稳定超薄Zr硅酸盐

Among them, ZrO/sub 2/ and its silicates are considered to be the most promising candidates. In this study, we report on the electrical and physical properties of ultra-thin Zr Silicate/ZrO/sub 2/ films deposited by the jet-vapor-deposition (JVD) process. It is shown that films with equivalent oxide thickness (EOT) of 1 nm, with high thermal stability, low leakage and good electrical properties can be fabricated. Our analysis also shows that the compositions of JVD films vary with the thickness. Thinner films are found to be Zr-silicate-like, whereas thicker films appear to be graded with a transition to stoichiometric ZrO/sub 2/. The presence of a Zr silicate interfacial layer may prevent the formation of interfacial SiO/sub 2/, despite the fact that as-deposited films are found to be oxygen rich. In contrast to other ZrO/sub 2/ films reported in the literature, the EOTs of our films decrease after post deposition annealing. Another remarkable observation is that the JVD Zr silicate film can survive an annealing temperature as high as 1000/spl deg/C, suggesting that it can be used in a conventional CMOS process without the need for a replacement gate process.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.

This paper presents a detailed study on the performance leverage of \"taped gate\" in a partially-depleted silicon-on-insulator (PD/SOI) technology. It is shown that because the reduced junction capacitance in the PD/SOI device renders the series resistance reduction of the lower transistors in the stack more effective, a \"tapered gate\" in PD/SOI technology has slightly larger improvement in the rising-input delays for the higher pins and slightly larger degradation on the lower pin falling-input delays compared with bulk CMOS technology. The effects are also shown to be more pronounced for low-V/sub T/ cases.
