    The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or a schematic design application that supports external simulators, such as KiCad or gEDA.

    It features Seven of Nine attempting to mother ex-Borg orphans, while USS Voyager encounters a unique alien species, the Kobali. [1] The episode was nominated for an Emmy award for makeup, by a team including Michael Westmore. The episode aired on the television channel UPN on March 1, 2000. [2]

  4. Regenerative circuit - Wikipedia

    en.wikipedia.org/wiki/Regenerative_circuit

    The type 36 screen-grid tube (obsolete since the mid-1930s) had a non-regenerative detection gain (audio frequency plate voltage divided by radio frequency input voltage) of only 9.2 at 7.2 MHz, but in a regenerative detector, had detection gain as high as 7,900 at critical regeneration (non-oscillating) and as high as 15,800 with regeneration ...

    en.wikipedia.org/wiki/Radio_receiver_design

    Classical regenerative receiver using a single triode vacuum tube. The orientation of the "tickler" coil was carefully adjusted by the operator in order to vary the amount of positive feedback. The regenerative receiver also had its heyday at the time where adding an active element (vacuum tube) was considered costly. In order to increase the ...

  6. Regenerator (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Regenerator...

    A regenerator in a telecommunications context is a type of repeater that is used in copper line or optical fibre line transmission systems. The regeneration function involved also appears in other types of systems, e.g. computer networking systems.

    The generated netlist is then read into a layout tool and associated with the footprints of the devices from a library. Placing and routing the devices can now start. [1] Placing and routing is generally done in two steps. Placing the components comes first, then routing the connections between the components. The placement of components is not ...

  8. Power-on reset - Wikipedia

    en.wikipedia.org/wiki/Power-on_reset

    In VLSI devices, the power-on reset (PoR) is an electronic device incorporated into the integrated circuit that detects the power applied to the chip and generates a reset impulse that goes to the entire circuit placing it into a known state.

  9. Electric (software) - Wikipedia

    en.wikipedia.org/wiki/Electric_(software)

    Unlike other systems that design integrated circuits (ICs) by manipulating polygons on different layers of the wafer, Electric views IC layout as connected circuitry, similar to the way schematic capture systems work. [7] [8] In Electric, designers place nodes (transistors, contacts, etc.) and connect them with arcs (wires). This has advantages ...
