This paper presents a statistical leakage estimation method for FinFET devices considering the unique width quantization property. Monte Carlo simulations show that the conventional approach underestimates the average leakage current of FinFET devices by as much as 43% while the proposed approach gives a precise estimation with an error less than 5%.

This paper presents a new compact outside-rail circuit structure for future scaled CMOS technology. The proposed circuit is composed of only two transistors connected into a single cascode style for increasing supply voltage to one more nominal supply voltage (VDD ). The circuit is manufactured and measured. Reliability is also verified by the trajectory plot for gate-source voltage and gate-drain voltage of all devices. The results confirm that triple of nominal supply voltage can be used without any overstress in all CMOS devices. The proposed circuit saves 52% area and improves speed for 40% of the conventional approach in the case of 4VDD. An example of outside-rail opamp is also proposed by using the proposed circuit

Wireline equalization using pulse-width modulation 使用脉宽调制的有线均衡
Pub Date : 2006-09-10 DOI: 10.1109/CICC.2006.320827

High-speed data links over copper cables can be effectively equalized using pulse-width modulation (PWM) pre-emphasis. This provides an alternative to the usual 2-tap FIR filters. The use of PWM pre-emphasis allows a channel loss at the Nyquist frequency of ~30dB, compared to ~20dB for a 2-tap symbol-spaced FIR filter. The use of PWM fits well with future high-speed low-voltage CMOS processes. The filter has only one `knob', which is the duty-cycle. This makes convergence of an algorithm for automatic adaptation straightforward. Spectral analysis illustrates that, compared to a 2-tap FIR filter, the steeper PWM filter transfer function fits better to the copper channel. This applies to both half-symbol-spaced and symbol-spaced 2-tap FIR filters. Circuits for implementation are as straightforward as for FIR pre-emphasis. In this paper new measurements are presented for a previous transmitter chip, and a new high-swing transmitter chip is presented. Both coaxial and differential cables are used for the tests. A bit rate of 5 Gb/s (2-PAM) was achieved with all cable assemblies, over a cable length of up to 130 m. Measured BER at this speed is <10-12
高速数据链路上的铜电缆可以有效地均衡使用脉冲宽度调制(PWM)预强调。这为通常的2抽头FIR滤波器提供了一种替代方案。与2分接符号间隔FIR滤波器的~20dB相比,PWM预强调的使用允许奈奎斯特频率下的信道损耗为~30dB。PWM的使用很适合未来的高速低压CMOS工艺。滤波器只有一个“旋钮”,即占空比。这使得自动适应算法的收敛性变得简单明了。频谱分析表明,与2抽头FIR滤波器相比,更陡峭的PWM滤波器传递函数更适合铜通道。这适用于半符号间隔和符号间隔的2抽头FIR滤波器。实现电路与FIR预强调一样简单。本文提出了一种新型的高摆幅发射芯片,并对原有的发射芯片进行了新的测量。同轴电缆和差分电缆都用于测试。所有电缆组件实现了5 Gb/s (2-PAM)的比特率,电缆长度可达130米。在此速度下测得的误码率<10-12

Performance verification is critical to high-performance ASICs manufacturing. Performance verification ensures that only those chips whose performance is higher than an advertised threshold are shipped to demanding customers. This provides a means to weed out nominal performance ASICs, and also ship ASICs at difference grades. At-speed structural test can provide performance verification capability at very low cost. In this paper, we present a scalable and flexible structural test method for performance verification of ASICs. The proposed method requires no tight restrictions on the circuit design. Moreover, low-cost testers are used, thus sharply reducing test cost

Low-noise, low-dropout (LN-LDO) regulators are critical for supply regulation of deep-submicron analog baseband and RF system-on-chip designs. A low 1/f noise LDO regulator utilizing a chopper stabilized error amplifier is presented. In order to achieve fast response during load transients, a current-mode feedback amplifier (CFA) with an asymmetrical input pair is designed as a second stage. With chopping frequencies up to 1MHz, an output noise spectral density of 32nV/radicHz and PSR of 38dB is achieved at 100kHz. Compared to an equivalent noise density static regulator, the error amplifier silicon area is reduced by 75%. With the current-mode feedback second stage buffer, settling time is reduced by 60% in comparison to an equivalent power consumption voltage mode buffer, achieving 0.6musec settling time for a 50mA load step. The LN-LDO is designed and fabricated on a 0.25 mum CMOS process with five layers of metal, occupying 0.88mm2

In this paper the theoretical operation of incremental (charge-balancing) delta-sigma (DeltaSigma) converters is reviewed, and the implementation of a 22-bit incremental A/D converter is described. Two different analyses of the first-order incremental converter are presented, and based on these results two extensions to higher-order modulators are proposed. Since line-frequency noise suppression is often important in measurement applications, modulators followed by sinck filters are also analyzed. Equations are derived for the estimation of the required number of cycles for a given resolution and architecture. Finally, the design and implementation of a third-order incremental converter with a fourth-order sine filter is briefly discussed
本文综述了增量式(电荷平衡)δ - σ (DeltaSigma)转换器的理论工作原理,并描述了一个22位增量式a /D转换器的实现。对一阶增量变换器进行了两种不同的分析,并在此基础上提出了对高阶调制器的两种扩展。由于线频噪声抑制在测量应用中通常是重要的,因此还分析了调制器后的sinck滤波器。在给定的分辨率和结构下,导出了估算所需循环数的方程。最后,简要讨论了带四阶正弦滤波器的三阶增量变换器的设计与实现

Two different analyses of the first-order incremental converter are presented, and based on these results two extensions to higher-order modulators are proposed. Since line-frequency noise suppression is often important in measurement applications, modulators followed by sinck filters are also analyzed. Equations are derived for the estimation of the required number of cycles for a given resolution and architecture. Finally, the design and implementation of a third-order incremental converter with a fourth-order sine filter is briefly discussed","PeriodicalId":269854,"journal":{"name":"IEEE Custom Integrated Circuits Conference 2006","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129601870","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}
