We have proposed and verified an efficient architecture for a high-speed I/O transceiver design that implements far-end crosstalk (FEXT) cancellation. In this design, TX pre-emphasis, used traditionally to reduce ISI, is combined with FEXT cancellation at the transmitter to remove crosstalk-induced jitter and interference. The architecture has been verified via simulation models based on channel measurement. A prototype implementation of a 12.8Gbps source-synchronous serial link transmitter has been developed in TSMC's 0.18mum CMOS technology. The proposed design consists of three 12.8Gbps data lines that uses a half-rate PLL clock of 6.4GHz. The chip includes a PRBS generator to simplify multi-lane testing. Simulation results show that, even with a 2times reduction in line separation, FEXT cancellation can successfully reduce jitter by 51.2 %UI and widen the eye by 14.5%. The 2.5 times 1.5 mm2 core consumes 630mW per lane at 12.8Gbps with a 1.8V supply

A 2.4GHz power amplifier is implemented with standard thin-oxide transistors in a 1.2V, 0.13 mum CMOS process. The output matching network is fully integrated on chip. The PA transmits up to 24dBm linear power with 25% drain efficiency at -1dB compression point. When driven into saturation, it transmits 27dBm peak power with 32% drain efficiency. A technique for enhancing average efficiency is proposed and demonstrated. This technique does not degrade instantaneous efficiency at peak power and maintains constant power gain with power back-off

This paper describes a broadband CMOS amplifier for differential receiver front-ends. A capacitive cross-coupling network provides passive gmboosting in the input cascode stage. This results in a greater than 30% increase in bandwidth. Combined with several other established bandwidth-enhancement techniques, the prototype achieves a measured 3-dB bandwidth of 19 GHz with no peaking in a 0.18-μm CMOS process. The dc gain is 11 dB differential, and the power consumption is 113 mW. Eye diagrams up to 24 Gb/s are shown.

We propose a novel traveling-wave oscillator (R2TWO) that uses reflection and regeneration of waves on a transmission line to generate multi-GHz square wave signals. We also propose a scalable, low-power, low-skew and low-jitter clock distribution network by tiling the basic R2TWO s in a regular fashion. Measurement results of a TSMC 0.18mum CMOS test chip show that it can generate and distribute near full-swing 6.5GHz global clock signals with power saving of more than 75% (compared with a traditional ring oscillator). The measured jitter is less than 0.84ps, and the skew less than 1.3ps

An Anti-Harmonic Locking, DLL Frequency Multiplier with Low Phase Noise and Reduced Spur 一种具有低相位噪声和减小杂散的抗谐波锁紧DLL倍频器
Pub Date : 2006-09-01 DOI: 10.1109/CICC.2006.320973
Q. Du, J. Zhuang, T. Kwasniewski
This paper presents a new programmable delay-locked loop based frequency multiplier with a period error compensation loop (PECL) designed to reduce the output spurious power level. The low bandwidth auxiliary PECL compensates the output period error caused by the in-lock errors from various noise sources. By employing a novel switching control scheme, the circuit is capable of locking to frequencies either above or below the start up frequency without initialization. Programmable multiplication ratios from 13 to 20 are achieved with an output frequency range of 900 MHz to 2.9 GHz. The circuit is implemented in TSMC 0.18mum CMOS technology and measured with the reference signal from an RF signal generator. A 23 dB spur reduction from -23dB to -46.5dB at 1.216GHz is observed from the measurement results. The measured cycle-to-cycle timing jitter at 2.16GHz is 1.6ps (rms) and 12.9 ps (pk-pk), and the measured phase noise is -110 dBc/Hz at 100 kHz offset with a power consumption of 19.8 mW at a 1.8 V supply
本文提出了一种基于可编程锁相环的新型倍频器,该倍频器采用周期误差补偿环(PECL)来降低输出杂散功率。低带宽辅助PECL补偿了各种噪声源的锁相误差引起的输出周期误差。通过采用一种新颖的开关控制方案,电路能够锁定到高于或低于启动频率的频率,而无需初始化。可编程乘法比为13至20,输出频率范围为900 MHz至2.9 GHz。该电路采用台积电0.18 μ m CMOS技术实现,采用射频信号发生器的参考信号进行测量。从测量结果中可以观察到1.216GHz时从-23dB到-46.5dB的23db杂散降低。在2.16GHz频率下,测量到的周期间时序抖动分别为1.6ps (rms)和12.9 ps (pk-pk),在100khz偏置时测量到的相位噪声为-110 dBc/Hz,在1.8 V电源下的功耗为19.8 mW

A memory sense-amplifier self-calibrates during sense-line precharge to reduce the required signal development and minimize data capture timing uncertainty caused by random device variation. When compared to conventional single-ended sensing, this method reduces sense time by 70% and decreases sense-power by 40%. The self-referenced sensing scheme (SRSS) is used to implement the search operation in content-addressable memory (CAM) testchip. Fabricated in 1V 65nm CMOS, this scheme achieves a 0.6ns search time on a 70bit sense-line while consuming only 0.99 fJ/bit/search. Measured search access time on a five bank 64times240bit ternary CAM including selective precharge is 2.2ns. Measured power consumption at 450MHz is 10mW. Hardware shows robust search operation over a voltage range of 0.6V to 1.7V

In this paper, a CMOS image sensor with on-chip compression processor is proposed. An adaptive quantization scheme based on boundary adaptation procedure followed by an on-line quadrant tree decomposition processing is proposed enabling low power, robust and compact image compression processor. The image sensor chip has been implemented using 0.35 mu CMOS technology and operates at 3.3 V. Simulation and experimental results show compression figures corresponding to 0.6-0.8 BPP, while maintaining reasonable PSNR levels and very low operating power consumption
本文提出了一种带有片上压缩处理器的CMOS图像传感器。提出了一种基于边界自适应过程和在线象限树分解处理的自适应量化方案,使图像压缩处理器具有低功耗、鲁棒性和紧凑性。该图像传感器芯片采用0.35 mu CMOS技术实现,工作电压为3.3 V。仿真和实验结果表明,在保持合理的PSNR水平和极低的运行功耗的情况下,压缩数字对应于0.6-0.8 BPP
