Free circuit simulation - SPICE and beyond
نویسنده
چکیده
SPICE is a de-facto standard for free circuit simulation and the role model for most commercial simulators. In this paper we present the SPICE OPUS circuit simulator which is based on the SPICE3 source code. The shortcomings of the original SPICE3 and of its device models are highlighted. We present the solutions to these shortcomings that were implemented in SPICE OPUS. Three promising open-source projects that do not resort to SPICE3 source code are discussed: Gnucap, QUCS, and fREEDA.

Modeling the Quantization Effects in Digital Filters via Spice- Family Programs
The paper describes an unusual approach of employing the SPICE-family circuit simulation programs in a simple analysis of digital filters, including the quantization effects. For explanation and demonstration, the evaluation version of OrCad PSpice v.15.7 is used which is available free on the Internet.
متن کاملOutput-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...
متن کاملan Efficient Drive Circuit for Switched Reluctance Motor
The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
متن کاملPspice Simulation of Power Electronics Circuit and Induction Motor Drives
Historically, simulation of transient phenomena related to power systems has been carried on using the electromagnetic transients program (EMTP) [1] or one of its variants, such as the alternative transient program (ATP) or electromagnetic transients for dc (EMTDC), which are all based on the trapezoidal integration rule and the nodal approach. These software packages use fixed-step algorithms,...
متن کاملDesign & Simulation of Cmos Inverter at Nanoscale beyond 20nm
The two major things, size and power consumption are very important parameter for any digital circuit design. Because all of us want to use the equipments that have compact in size and less power consumption, this paper investigates the applications of CMOS technology in the nanometer regime beyond 20 nm channel length where the relative study of average power dissipation of CMOS inverter is fo...
