The paper reports a novel 0.8 V CMOS true-single-phase-clocking (TSPC) adiabatic differential cascode voltage switch (DCVS) logic circuit with the bootstrap technique for low-power VLSI. Via the pass transistors and compensating transistors, the TSPC scheme has been obtained for easy clocking. Using the capacitance coupling from the bootstrap transistors, this 0.8 V TSPC adiabatic DCVS logic circuit with the bootstrap technique consumes 31% less energy as compared to the one using the clocked adiabatic latch (CAL) approach.

The VLSI implementation of the universal two-dimensional (2D) cellular automata transform (CAT) as well as inverse CAT (ICAT) is present in this paper. The universal 2D CAT/ICAT chip is based on the 2D CAB generator. To facilitate the development of a universal 2D CAB generator, we adopted a CA cell structure with programmable additive rules to generate 1D CAB first, and then utilized the canonical products of 2D CAB to perform the 2D CAB. We have accomplished simulations of the universal 2D 8/spl times/8 CAT/ICAT chip by using CANDENCE tools. We also have completed the circuit synthesis of the 2D CAT/ICAT chip by using the SYNOPSE tools with the TSMC 0.35 /spl mu/m CMOS data-path cell-library. The maximum operation frequency was 120 MHz, and the area size was 6.8225 mm/sup 2/. It shows that the architecture of the proposed universal 2D CAT/ICAT is suitable for VLSI realization.

Single-bit delta-sigma (/spl Delta//spl Sigma/) modulation reduces the complexity of receive beamformers in ultrasound and sonar imaging applications. These applications, however, require a sampling rate in excess of 220 MHz due to the high bandwidth of the echo signals. In this paper, the design and implementation of a 250 MHz second-order single-bit /spl Delta//spl Sigma/ modulator suitable for ultrasound/sonar applications is presented. The circuit is realized in a 0.18 /spl mu/m P-well CMOS technology and dissipates 20 mW average power when clocked at 250 MHz. The area of the circuit is 0.24 mm/sup 2/. Post-layout simulations show that the modulator achieves 48 dB maximum SNR and 50 dB dynamic range for a 5 MHz input signal bandwidth.

Design, operation and measurement results of a CMOS camera implemented within a SOI wafer are presented. The peak of photodiode quantum efficiency is obtained for the wavelengths of 400-500 nm. In addition, noise measurements of the 1/f noise in P-MOS and N-MOS transistors for analog applications are reported under wide bias conditions ranging from subthreshold to saturation. Two implementations (in regular and SOI wafers) of 0.35 /spl mu/m CMOS analog process are compared and it is found that they exhibit similar 1/f noise. The results of this study are useful to the design and modeling of 1/f noise of CMOS analog circuits.

A highly resolved carrier and information extraction of an optically modulated radar signal is presented. The extraction is done by passing the optical beam through a monitoring path that realizes an FIR filter. Replications of the monitoring signal realize the required spectral scan of the filter. Despite the fact that the filter configuration is fixed, each replication experiences different spectral filtering. The radar carrier is detected by observing the energetic fluctuations in a low rate detector. The RF information is extracted by positioning a low rate tunable filter at the detected carrier frequency.

B. Taskin, I. Kourtev
The paper addresses the advanced timing analysis of multiphase level-sensitive synchronous circuits under clock skew scheduling (Kourtev, I.S. and Friedman, E.G., "Optimization Through Clock Skew Scheduling", Kluwer Academic Publishers, 2000). The timing analysis framework previously offered for a single-phase clocking scheme (Taskin, B. and Kourtev, I.S., Proc. 15th IEEE Int. ASIC/SOC Conf. p.358-62, 2002) is enhanced to accommodate a multiphase clocking scheme. In particular, the timing analysis framework is used to formulate the clock period minimization problem of multiphase level-sensitive circuits. The modified big M method of Taskin and Kourtev is used to linearize the formulation of the clock period minimization problem and experiments are performed on the ISCAS'89 benchmark circuits. In single-phase level-sensitive circuits, up to 63% improvements over conventional zero clock skew, edge-triggered circuits are achieved through the simultaneous application of non-zero clock skew scheduling and time borrowing. Comparable improvements of up to 62% are achieved for the same circuit topologies under a multiphase clocking scheme.

Several studies demonstrated that network traffic exhibits self-similarity and long-range dependence. Of the new methods for modeling self-similar traffic, the pseudo self-similar traffic model (PSST) (Robert and Le Boudec (1997)) is especially attractive since it is simple, has only two parameters to fit and is readily analyzed by classical queueing theory methods. In this paper we perform a performance evaluation of the PSST model by investigating its suitability to model the queueing behavior of self-similar traffic. We simulate a system fed by self-similar traffic traces with a single server and geometrically distributed service times. The observed steady state queue size distribution is compared to the one predicted by a PSST model fitted to the parameters of the traffic traces.
