This paper describes the initial development of a translator from VHDL-AMS code into HSPICE, as a contribution to the group of CAD-EDA tools in the field of analog design. Analog synthesis tools are not as developed as digital ones but the arise of VHDLAMS, a superset of VHDL, can help to their development. In this work, we present some features of a translator capable to synthesise analog circ...

Three standard 1/f noise models for MOSFETs are actually implemented in software packages: SPICE, HSPICE and recently BSIM3v3 noise model. The aim of this contribution is to show the limitation for each of these implementations by comparing noise simulations to noise measurement data. We demonstrated that 1/f noise model implemented in SPICE and HSPICE can not predict correctly noise in all ope...

This paper presents a novel low-power and high-speed 1-bit full-adder, which is designed based on pass transistor and TG logics. The main advantage of this design is low propagation delay and lowpower consumption, which leads to achieving lower PDP than others. Intensive HSPICE simulation shows that the new full-adder consumes around 28.5% less power than 14T adder; moreover its PDPis 30% less ...

Received Mar 14, 2014 Revised Jun 18, 2014 Accepted Jul 4, 2014 In many Engineering applications, analog circuits present many advantages over their digital counterparts and have recently been particularly used in a wide range of signal processor circuits. In this paper, an analog non-linear function synthesizer is presented based on a polynomial expansion model. The proposed function synthesiz...

In this article different types of artificial neural networks (ANN) were used for CNTFET (carbon nanotube transistors) simulation. CNTFET is one of the most likely alternatives to silicon transistors due to its excellent electronic properties. In determining the accurate output drain current of CNTFET, time lapsed and accuracy of different simulation methods were compared. The training data for...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...

With current aggressive down scaling of critical dimensions (CD) in integrated circuits (IC) technologies, the impact of variations on the amount of power and performance variance of a system is growing. At present, in large scale IC designs one of the main concerns is the position dependant variations or simply spatial variation. Using different regions on a chip and defining a correlation mat...

This study proposes a new behavioral simulator that uses SIMULINK for all-digital CMOS time-domain smart temperature sensors (TDSTSs) for performing rapid and accurate simulations. Inverter-based TDSTSs offer the benefits of low cost and simple structure for temperature-to-digital conversion and have been developed. Typically, electronic design automation tools, such as HSPICE, are used to simu...
