We present the structure of an analog integrated circuit design laboratory to instruct at both, senior undergraduate and entry graduate levels. The teaching material includes: a laboratory manual with analog circuit design theory, pre-laboratory exercises and circuit design specifications; a reference web page with step by step instructions and examples; the use of mathematical tools for automa...

This paper presents simple lumped element equivalent circuit for the coplanar waveguide (CPW) square spiral inductor. The circuit is based on physical modelling which takes into consideration the parasitic effects inherent in the CPW spiral inductor. The obtained scattering parameters are in good agreement with fullwave and quasi-static results available in the literature. Such a simple circuit...

-In this paper a 4 bit parallel adder/subtractor circuit has been designed and analyzed. The circuit uses a controlled adder/subtractor circuit which converts the negative numbers into their 2’s complement. A comparative study of the silicon area and the power consumption has been done in the circuit using different channel lengths such as 65nm, 45nm. The circuit is designed and simulated using...

Integrated-circuit interconnect characterization is growing in importance as devices become faster and smaller. Along with this trend, interconnect geometry is becoming more complex, consisting of an increasing number of wiring levels. Accurate numerical extraction of three-dimensional (3-D) interconnect capacitance is essential for achieving design targets in the multigigahertz digital regime....

VLSI technology CAD (TCAD) requires integrated, physics-based tools for predictive process, device, and (small-scale) circuit simulation. Computational efficiency is desirable, and indeed essential if the TCAD system is to be used in manufacturing CAD involving statistical simulation. Conventional TCAD systems comprise robust, numerical process and device simulators which drive optimization of ...

Advanced CAD tools and high-density VLSI technologies have combined to create a new market for reusable digital designs. The economic viability of the new core-based design paradigm is pending on the development of techniques for intellectual property protection. A design watermark is a permanent identification code that is difficult to detect and remove, is an integral part of the design, and ...

The evolutionary multiobjective optimization technique for analog circuit optimizer is presented in this paper. the technique uses a Parallel Genetic Algorithm(PGA) to identifies multiple “good” solutions from a multiobjective fitness landscape which are tuned using a local hill-climbing algorithm. The PGA is used to provide a nature niching mechanism that has considerable computational advanta...

We present a formula of short-circuit power dissipation for static CMOS logic gates. By representing short-circuit current by a piece-wise linear function and considering a current flowing from input node to output node through gate capacitances, the accuracy is improved significantly. The error of our formula in a CMOS inverter is less than 15% from circuit simulation in most cases of our expe...

A generalized parameter-level statistical MOS model, called SMOS, capable of generating statistically significant model decks from intraand inter-die parameters statistics is described. Calculated model decks preserve the inherent correlations between model parameters while accounting for the dependence of parameter variance on device separation distance and device area. Using a Monte Carlo app...
