Opis:
Equation-defined non-linear functional elements are important building blocks in the development of compact semiconductor device models. Current trends in compact device modelling suggest widespread acceptance among the modeling community of Verilog-A, for semiconductor device specification, model exchange and circuit simulation. This paper outlines techniques for the development of adaptive EPFL-EKV long and short channel MOS models which stress user selectable model features and diagnostic capabilities. Adaptive EPFL-EKV nMOS models based on Verilog-A and Modelica are introduced and their performance compared with simulation data obtained using the "Quite universal circuit simulator" (Qucs), SPICE and the Modelica simulation environment.

Opis:
SPICE AC circuit simulation is fundamentally a small signal network analysis of a linear or non-linear circuit operating at specified DC bias conditions, where the electrical network component values are assumed not to be functions of AC input signal frequency. In the case of RF circuit simulation this assumption can give rise to significant modelling errors. With the recent improvements in General Public License (GPL) circuit simulators this situation is changing, particularly through the introduction of Frequency Dependent Equation-Defined Device (FEDD) models, non-linear current/voltage static and dynamic Equation-Defined Device (EDD) models and user controlled swept signal frequency simulation employing Harmonic Balance steady state analysis. The main purpose of this paper is to introduce a number of novel modelling and circuit simulation techniques that allow, and enhance, the construction of compact device models with embedded behavioural components whose non-linear properties are functions of AC input signal frequency. To demonstrate these new modelling techniques a compact model for a 10 GHz band width spiral inductor integrated on silicon is introduced, its compact model presented, and finally its simulation performance compared with published measured device data.

Opis:
This paper is concerned with the development and evaluation of a number of modeling techniques which improve Qucs Harmonic Balance simulation performance of RF compact device models. Although Qucs supports conventional SPICE semiconductor device models, whose static current/voltage and dynamic charge characteristics exhibit second and higher order derivatives may not be continuous, there is no guarantee that these will function without Harmonic Balance simulation convergence problems. The same comment also applies to a number of legacy compact semiconductor device models. The modeling of semiconductor devices centered on non-linear Equation-Defined Devices and blocks of Verilog-A code, combined with linear components, is introduced. These form a class of compact macromodel that has improved Harmonic Balance simulation performance. To illustrate the presented modeling techniques RF diode, BJT and MESFET macromodels are described and their Harmonic Balance performance simulated with Qucs and Xyce©.

Opis:
The Qucs Equation-Defined Device was introduce roughly ten years ago as a versatile behavioural simulation component for modelling the non-linear static and dynamic properties of passive components, semiconductor devices and IC macromodels. Today, this component has become an established element for building experimental device simulation models. It’s inherent interactive properties make it ideal for device and circuit modelling via Qucs schematics. Moreover, Equation-Defined Devices often promote a clearer understanding of the factors involved in the construction of complex compact semiconductor simulation models. This paper is concerned with recent advances in Qucs-S/Ngspice/XSPICE modelling capabilities that improve model construction and simulation run time performance of Equation-Defined Devices using XSPICE model syntheses. To illustrate the new Qucs-S modelling techniques an XSPICE version of the EPFL EKV v2.6 long channel transistor model together with other illustrative examples are described and their performance simulated with Qucs-S and Ngspice.

Opis:
A high percentage of analogue integrated circuit designs use voltage domain signal processing techniques. Given the fact that integrated circuit current conveyors are high bandwidth current processing devices, often with superior RF performance compared to comparable voltage domain devices, it is surprising that the number of current mode integrated circuits available, as standard of-the-shelf industrial items, is so small. This paper introduces equation-defined device and Verilog-A synthesis approaches to the macromodelling of current conveyor integrated circuits. To illustrate the proposed modelling techniques the properties of a number of modular behavioural level current conveyor macromodel cells are described and their performance compared. The material presented is intended for analogue device modellers and circuit designers who wish to simulate large signal current domain integrated circuit designs. It also demonstrates how synthesized Verilog-A modules can be derived from equation-defined device and conventional subcircuits to form functional, computationally efficient current conveyor macromodels. To illustrate the application of behavioural current conveyor macromodels the design of a six cell CCII+ instrumentation amplifier is introduced and its performance discussed.
