Quite Universal Circuit Simulator – Qucs

An integrated circuit simulator. Sketch the circuit and simulate the large-signal, small-signal and noise behavior of the circuit. After that simulation has finished you can generate and display the simulation results on the presentation output page.

The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available. Qucs can also import existing SPICE models for use in your simulations.

EDA and Technical Software Components

  • ADMS — Verilog-A translator
  • ps2sp.pl — A SPICE preprocessor
  • ASCO (A SPICE Circuit Optimizer)
  • FreeHDL — for VHDL digital simulations
  • Icarus Verilog — for Verilog-HDL digital simulations
  • GNU Octave — for Octave interactive interface
GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation.

“Some people collect stamps, coins or baseball cards, I collect electronic circuit schematics. I own several book shelves and file cabinets full of electronic circuit books, IC application manuals and circuit encyclopedias. I often use my collection for reference.”

“These switch circuits used a sensitive high impedance circuit to detect the small AC power line signals, picked up by the human body from nearby appliances.”

(These are the type of technologies that lead to the Touch Screens on Tablets and Phones.

USB.org – Universal Serial Bus and Wireless USB

Universal Serial Bus (USB) connects more than computers and peripherals. It has the power to connect you with a whole new world of PC experiences.

USB.org – Universal Serial Bus

USB Implementers Forum, Inc. is a non-profit corporation founded by the group of companies that developed the Universal Serial Bus specification.

Wireless USB - Wireless Extension to USB

Wireless USB – Wireless Extension to USB

Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices.

Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.

Wireless USB will support robust high-speed wireless connectivity by utilizing the common WiMedia MB-OFDM Ultra-wideband (UWB) radio platform as developed by the WiMedia Alliance.

I saw this innovation earlier. Wireless USB – Wireless Extension to USB. And also a USB Drive like product.
