This paper presents application and effectiveness of Hierarchical particle swarm optimization (HPSO) algorithm for automatic sizing of low-power analog circuits. For the purpose of comparison, circuits are also designed using PSO and Genetic Algorithm (GA). CMOS technologies from 0.35 μm down to 0.13 μm are used. PVT (process, voltage, temperature)(More)
A new lookup-table (LUT) approach, based on normalization of the drain current with an <i>I</i> <sub>D</sub>-<i>V</i> <sub>G</sub> template, is proposed for simulation of MOS transistor circuits. The LUT approach is validated by considering two examples and by comparing the LUT results with mixed-mode (device-circuit) simulation results. This approach is(More)
A new public-domain simulator for power electronic circuits is described. The organization of the simulator is briefly discussed. The most important feature of the simulator is that the user can define new elements in a flexible manner. The differences between the new simulator and other simulators are enumerated. Some simulation examples are discussed to(More)
In this paper, we study the circuit performance issues of high-K gate dielectric MOSFETs using the Look-up Table (LUT) approach. The LUT approach is implemented in a public-domain circuit simulator SEQUEL. We observed an excellent match between LUT simulator and mixed mode simulations using MEDICI. This work clearly demonstrates the predictive power of the(More)
A generalized methodology for modeling the effects of process variations on circuit delay performance is proposed by directly relating the variations in process parameters to variations in delay metric of a digital circuit. The 2-input nand gate is used as a library element for 65 nm gate length technology, whose delay is extensively characterized by(More)
OBJECTIVES To investigate the effect of the aqueous extract of Phyllanthus niruri (Aq.E.PN) against doxorubicin (Dox)-induced myocardial toxicity in rats. MATERIALS AND METHODS Cardiotoxicity was produced by Dox administration (15 mg/kg for 2 weeks). Aq.E PN (200 mg/kg, orally) was administered as pretreatment for 2 weeks alternated with Dox for the next(More)
