This paper presents a method for automated design of such circuits. By combining equations and heuristics with simulation-corrections, it allows to achieve the accuracy of optimization-based sizing with the speed of knowledge-based sizing one. The correction scheme is also used to reduce the number of independent variables. Sizing, speed and accuracy allow it to be used in the design and technology migration of digital libraries, full-custom cells as well as dynamically during timing analysis to compensate long critical paths. Applications are also appealing for highly non-linear analog functions. A prototype tool has been implemented in MATLAB.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The fabricated TFTs show an ON/OFF ratio of 4/spl times/l0/sup 4/. All of the fabrication steps have been done at temperatures as low as 130/spl deg/C. A recently established stress-assisted copper-induced crystallization technique has been exploited to crystallize the amorphous Ge (a-Ge) layer. Mechanical compressive stress has been applied to the Ge layer by bending the flexible substrate inward. Proper patterning of the a-Ge layer before thermo-mechanical post-treatment alleviates the density of cracks induced in the Ge layer as the main repercussion of the interfacial stress.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The cost is an increase of pole zero complexity such that traditional open loop analysis will not lead to intuitive design equations. This paper introduces a systematic design approach of cascode compensated two stage OTAs. The parametric transfer function, settling error and thermal noise equations were first extracted from the small signal equivalent circuit of the OTA, then a set of poles and zeros which best suited settling requirements was asserted into the non-linear equations relating pole zero and circuit parameters, through which circuit parameters were calculated. Using the system level results Spice simulation of the OTA was performed in a 0.35 /spl mu/m CMOS process. The simulated OTA achieved a DC-gain of 100dB with a 120MHz bandwidth and a 62/spl deg/ phase margin from a 3V power supply. The measured dissipated power was 2.01 mW with a settling time of 7 nSec.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

A major constraint consists of \"Time-to-Market\". Hence, the emergence of SoC is creating many new challenges, especially, the necessity of a unified language for the system level design. SystemC is proposed as a standardized modeling language intended to enable system level design at multiple abstraction levels for hardware / software systems. This paper describes a method of stepwise refinement with SystemC, starting from an algorithmic description and progressively adding implementation details. The method is described with reference to a Turbo encoder, which is progressively moved from a purely abstract level to a more detailed description. This study is realized to emphasize on the importance of this tendency within the framework of SoC design. We also present the experimental results from specification, refinement and validation with SystemC and simulation effectiveness of the proposed method.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

In this method, we use a High Frequency (HF) standard CP measurement. We avoid the border-trap effect in CP current (I/sub cp/) measurements. Hence, I/sub cp/ is only due to the interface-trap contribution. We demonstrate that /spl Delta/N/sub ot/ is only dependent on /spl Delta/V/sub th/ (threshold voltage shift) and /spl Delta/I/sub cpm/ (augmentation of maximum CP current). We also show that /spl Delta/V/sub th/ can be obtained from lateral shift of CP Elliot curves and /spl Delta/I/sub cpm/ from vertical shift.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.
