Overview of QUCS - the Electronic Design and Automation Tool

Overview of EDA Tools

What You will Learn

  • You will familiarize the SPICE tool QUCS

Quite Universal Circuits Simulator(QUCS)

Quite Universal Circuits Simulator(QUCS) is an open source circuit simulation software, based on SPICE, that is built on the QT4 platform, that is especially useful in the simulation of high frequency circuits. The schematics of analog and digital circuits can be entered into the schematics editor and wired together and be subjected to the following simulations.

  • DC simulation
  • Transient simulation
  • AC simulation
  • S-parameter simulation
  • Parameter sweep simulation
  • Harmonic balance
  • Digital simulation
  • Optimization

Installation of QUCS

QUCS is installed on Ubuntu using the instructions here The executables for Qucs for Windows can be downloaded here . Click and run the .exe file to install QUCS.

Working with QUCS

  • Launch QUCS. The window you see is the editor below in which you will enter the schematics and wire them up.
  • The generic components are dropped from the components tab on the left pane
  • Components with specific part number and device identification are dropped from Tools → Components Library
  • The components are connected together using wires, initiated by pressing Cntrl + E
  • Once the circuit is completed, the required simulation type are dropped to the schematic window as Components → Simulations

    • Now let us look and the development and SPICE simulation of a voltage divide network in the next post.

Generation of Signals using MATLAB/Python

Generation of Signals using MATLAB/Python Dr. Hari V S Department of Electronics and Communication College of Engineering Karunagappally What You will Learn You will learn about various energy signals and their generation using MATLAB and python. Signal Generation using MATLAB MATLAB arrays are used to generate finite energy signals. It should be understood that the signals so generated are discrete in time and amplitude. Sinusoidal Signal Consider the sinusoidal signal $x=sin(t)$, which is nothing but a single tone, with the help of the MATLAB code below. t=linspace(0,10,5000); x=sin(t); plot(t,x); grid; The execution of the code will result in the signal, shown below. Amplitude Modulated Signal The above low frequency tone is used to modulate a sinusoidal carrier $y$ of ten times the original frequency. i.e. $y=sin(10t)$. The amplitude modulated signal $am(t)$ is obtained as \begin{equation} am(t)=x*y+y \end{equation}Su...

RC Coupled Amplifier

RC Coupled Amplifier Dr. Hari V S Department of Electronics and Communication College of Engineering Karunagappally What You will Learn You will understand the design of RC coupled amplifier. You will appreciate its frequency response and understand the variation of voltage gain at low and high frequencies. You will understand the effect of emitter bypass capacitor (or rather the effect of current series negative feedback) on the voltage gain and frequency response of the amplifier. You will understand the concept of stability of amplifier by analyzing the Nyquist plot and understand how negative feedback improves the stability. Objectives To design and implement RC coupled amplifier and to observe voltage amplification both in Qucs and on breadboard. To plot its frequency response curve and to compute the bandwidth with and without feedback. Design Let $V_{CC}=15V$, $\beta=200$ and $I_{C}=5mA$. For active region ...
