Electronics circuits PCBA Assembly,low cost Electronics circuit Shenzhen,CN China
Electronic Circuits Here are some neat circuits you might want to try. The schematics and printed circuit board patterns are GIF's, and may show up different on some browsers. You might want to save the images (especially the PC board patterns) to your hard drive, load them into a photo editor (Photoshop, Paint Shop Pro, The GIMP, etc.) and adjust the size before you transfer the pattern to a board. Printed circuit board patterns are available possible. This page is always under construction and there will be new additions from time to time. Some of these circuits were designed by me, most are not. Whenever possible I have tried to credit the author of a circuit but since many of these circuits are from my personal collection that I have gathered over a period of many years, this information is not always available.

My lawyer insisted that I add this DISCLAIMER: DiscoverCircuits.. is a collection of links to 26,000+ electronic circuits or schematics (more are added regularly). I have carefully categorized and cross-referenced each one for ease of selection into over 500 electronic circuit categories. Because I have not tested all these electronic circuits, I cannot attest to their accuracy; therefore, I do not provide a warranty of any kind and cannot be held responsible in any manner.

Analog, Digital, Symbolic, RF, VHDL, MCU and Mixed-Mode Circuit Simulation & PCB Design

TINA Design Suite is a powerful yet affordable software package for analyzing, designing and real time testing analog, digital, VHDL, MCU, and mixed electronic circuits and their PCB layouts. You can also analyze RF, communication, optoelectronic circuits, test & debug microcontroller applications. A unique feature of TINA that you can bring your circuit to life with the optional USB controlled TINALab II hardware which turns your computer into a powerful, multifunction T&M instrument. Electrical engineers will find TINA an easy to use, high performance tool, while educators will welcome its unique features for the training environment.

Easy to use schematic entry. Enter any circuit within minutes with TINA's easy-to-use schematic editor. Enhance your schematics by adding text and graphics elements such lines, arcs arrows, frames around the schematics and title blocks. Choose components from the large library containing more than 20,000 manufacturer models. You can check schematics for errors with TINA??s advanced ERC functions. The schematic editor supports complex hierarchical designs, team design and version control.

Powerful analysis tools. Analyze your circuit through more than 20 different analysis modes or with 10 high tech virtual instruments. Present your results in TINA's sophisticated diagram windows, on virtual instruments, or in the live interactive mode where you can even edit your circuit during operation, develop, run, debug and test VHDL & MCU applications.

Integrated PCB design. The new fully integrated layout module of TINA has all the features you need for advanced PCB design, including multilayer PCB??s with split power plane layers, powerful autoplacement & autorouting, rip-up and reroute, manual and ??follow-me?? trace placement, DRC, forward and back annotation, pin and gate swapping, keep-in and keep-out areas, copper pour, thermal relief, fanout, 3D view of your PCB design from any angle, Gerber file output and much more.

Advanced presentation tools. Make stand-out reports and presentations of schematic diagrams, annotations, formulas provided by symbolic analysis, Bode plots, Nyquist diagrams, poles and zeros, transient responses, digital waveforms, and other data using linear or logarithmic scales. Customize presentations using TINA's advanced drawing tools to control text, fonts, axes, line width, color and layout. You can create, edit and print documents directly inside TINA or cut & paste your results into your favorite word processing or DTP package.

Importing Spice models. Create new TINA components from any Spice subcircuit, whether created by yourself, downloaded from the Internet, obtained from a manufacturer's CD or from portions of schematics turned into subcircuits. TINA automatically represents these subcircuits as a rectangular block, but you can create any shape you like with TINA's Schematic Symbol Editor. You can also use TINA's parameter extractor program to calculate model parameters from catalog or measurement data and then add the new devices into the catalog.


Educational tools. TINA also includes unique tools for testing students' knowledge, monitoring progress and introducing troubleshooting techniques. With optional hardware it can be used to test real circuits for comparison with the results obtained from simulation.

Virtual Instruments: Oscilloscope, Function Generator, Multimeter, Signal Analyzer/Bode Plotter, Network Analyzer, Spectrum Analyzer, Logic Analyzer, Digital Signal Generator, XY Recorder.

Real time measurements. TINA is far more than a simulation software with virtual measurements. You can install optional, supplementary hardware that allows real-time measurements controlled by TINA's on screen virtual instruments.
