  2. Photodetector - Wikipedia

    en.wikipedia.org/wiki/Photodetector

    Such an electron is collected by a suitable external readout integrated circuits (ROIC) and transformed into an electric signal. LEDs which are reverse-biased to act as photodiodes. See LEDs as photodiode light sensors. Photoresistors or Light Dependent Resistors (LDR) which change resistance according to light intensity. Normally the ...

  3. Ladder logic - Wikipedia

    en.wikipedia.org/wiki/Ladder_logic

    Part of a ladder diagram, including contacts and coils, compares, timers and monostable multivibrators. Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required. Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits. As ...

  4. Circuit design - Wikipedia

    en.wikipedia.org/wiki/Circuit_design

    Costs for designing a circuit are almost always far higher than production costs per unit, as the cost of production and function of the circuit depends greatly on the design of the circuit. [ 11 ] Although the typical PCB production methods involve subtractive manufacturing, there are methods that use an additive manufacturing process, such as ...

  6. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

  7. Readout integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Readout_integrated_circuit

    Digital readout integrated circuit (DROIC) block diagram. A digital readout integrated circuit (DROIC) is a class of ROIC that uses on-chip analog-to-digital conversion (ADC) to digitize the accumulated photocurrent in each pixel of the imaging array. DROICs are easier to integrate into a system compared to ROICs as the package size and ...

  8. Electronic circuit simulation - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit_simulation

    Mixed-mode simulation is handled on three levels: with primitive digital elements that use timing models and the built-in 12 or 16 state digital logic simulator, with subcircuit models that use the actual transistor topology of the integrated circuit, and finally, with inline Boolean logic expressions.

  9. Transducer - Wikipedia

    en.wikipedia.org/wiki/Transducer

    A sensor is a transducer that receives and responds to a signal or stimulus from a physical system. [3] [4] [2] It produces a signal, which represents information about the system, which is used by some type of telemetry, information or control system. An actuator is a device that is responsible for moving or controlling a mechanism or system.
