electronic circuit design software

Fritzing is a set of software designed for PrintedCircuitBoard printed circuit boards. It is a tool especially intended for designers, artists, researchers, and amateurs. Like Processing and Arduino, Fritzing developers design this software in the spirit of openness, simplicity, and sharing. Fritzing is a simple and ea

1. "Protel" is mainly painted PCB, representative of PROTEL99, later developed to Altium Designer, more features.2. "OrCAD" is the main schematic diagram of the circuit and for the production of PCB and programmable logic design to provide continuous simulation information.3. "PSPICE" main analysis circuit. First, based on the analysis of the basic

mentor and Cadence is as ugly as it is. Especially that line. It's really not easy to draw a line that doesn't bend. Later, because of the relationship between a project and learn the mentor company software, give me the most impressive is the mouse gesture recognition, other because of the basis of CR-5000, learning is still very fast. Later I used cadence, orcad, some work needs, some self-taught, and not very deep. The general feeling is that no

#. Current amplification circuit is generally applicable to the situation where the resistance of the signal source is large and the load resistance is small. #. The above four circuit models can achieve arbitrary conversion between each other, a practical amplifier circuit in principle can take four of the circuit mo

Focus:Branch Current methodSuperposition theoremThévenin theorem.Electronic technology: Digital electricity, mold power.Equivalent transformation of 2.1 resistor series-Parallel connectionThe voltage of the current source is determined by the external circuit.The equivalent relationship between the ① voltage source model and the current source model is only the external circuit, which is not equivalent to the internal power supply.When the voltage sou

A circuit diagram usually has dozens of or even hundreds of, their lines cross, the form is changeable, beginners often do not know where to start, how to read it. In fact, the electronic circuit itself has a strong regularity, no matter how complex the circuit, after analysis can be found, it is composed of a few unit

In analog electronic technology, we need to master the basic structure of the basic components and the characterization of the main parameters from the contact of simple diodes to transistors (BJT) to integrated circuits. I will not elaborate on the internal components of diodes and transistors (BJT), which can be described in more detail by reference to the relevant information. In the transistor, a very important value is the static work point Q, t

ObjectiveThe last two days using AD14 software designed a Bluetooth anti-loss circuit board (PCB) drawings, the middle of some details in this document, to facilitate the next design of the PCB reference. Also hope to give the layman's classmates or just into the students a macro view of the General circuit board

Landlord said: This is mainly about an infrared remote control circuit principle and design, part four is the focus, with the circuit diagram to illustrate the specific process-receive, count, meet the conditions trigger control circuit!From elecfans:http://www.elecfans.com/article/88/131/198/2015/20151215394306.htmlFi

Circuit Design: This is a very big concept, from the voltage intensity can be divided into strong electric circuit design and Weak Current Circuit Design; from the design tool can be di

, the dielectric inside the battery can withstand a large amount of charging current, so the external can charge the lithium battery by a large amount of current, in order to shorten the charging time. The charging current in this phase is generally determined by a pin external to the charging management IC and a resistor. The resistance value is calculated based on the formula on the datasheet of the Charging management IC. 3. Constant Pressure Charging phase (already filled with more than 85%
