    en.wikipedia.org/wiki/List_of_free_electronics...

    List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.

  3. Arduino Uno - Wikipedia

    en.wikipedia.org/wiki/Arduino_UNO

    The word "uno" means "one" in Italian and was chosen to mark a major redesign of the Arduino hardware and software. [7] The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [4]

  4. Electronic circuit - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit

    Analog circuits are very commonly represented in schematic diagrams, in which wires are shown as lines, and each component has a unique symbol. Analog circuit analysis employs Kirchhoff's circuit laws: all the currents at a node (a place where wires meet), and the voltage around a closed loop of wires is 0. Wires are usually treated as ideal ...

  5. Analogue electronics - Wikipedia

    en.wikipedia.org/wiki/Analogue_electronics

    Analogue electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.

  6. Analog-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Analog-to-digital_converter

    The analog part of the circuit consists of a high input impedance buffer, precision integrator and a voltage comparator. The converter first integrates the analog input signal for a fixed duration and then it integrates an internal reference voltage of opposite polarity until the integrator output is zero.

  7. Load line (electronics) - Wikipedia

    en.wikipedia.org/wiki/Load_line_(electronics)

    In graphical analysis of nonlinear electronic circuits, a load line is a line drawn on the current–voltage characteristic graph for a nonlinear device like a diode or transistor. It represents the constraint put on the voltage and current in the nonlinear device by the external circuit.

  8. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    The circuit consists of an up-down counter with the comparator controlling the direction of the count. The analog output of the DAC is compared with the analog input. If the input is greater than the DAC output signal, the output of the comparator goes high and the counter is caused to count up. The tracking ADC has the advantage of being simple.

  9. Analog verification - Wikipedia

    en.wikipedia.org/wiki/Analog_Verification

    Analog verification is a methodology for performing functional verification on analog, mixed-signal and RF integrated circuits and systems on chip. [1] Discussion of analog verification began in 2005 when it started to become recognized that the analog portion of large mixed-signal chips had become so complex that a significant and ever-increasing number of these chips were being designed with ...
