  2. Multi-level converter - Wikipedia

    en.wikipedia.org/wiki/Multi-level_converter

    A multi-level converter (MLC) or (multi-level inverter) is a method of generating high-voltage wave-forms from lower-voltage components. MLC origins go back over a hundred years, when in the 1880s, the advantages of DC long-distance transmission became evident. [1] Modular multi-level converters (MMC) were investigated by Tricoli et al in 2017.

  3. Ćuk converter - Wikipedia

    en.wikipedia.org/wiki/Ćuk_converter

    The switch is typically a MOSFET, IGBT, or BJT transistor. The Ćuk converter [1] (Serbo-Croatian:, English: / ˈ tʃ uː k /) is a type of buck-boost converter with low ripple current. [2] A Ćuk converter can be seen as a combination of boost converter and buck converter, having one switching device and a mutual capacitor, to couple the energy.

    en.wikipedia.org/wiki/Message_Sequence_Chart

    A user tries to establish a connection. A connection request is sent to the switch and a timer is started. An alternative deals with two possibles responses: 1 - The timer goes off because the switch did not reply and the phone goes back to the disconnected state.2 - The switch grants the connection and the call is established.

    en.wikipedia.org/wiki/Reference_designator

    This standard codified information from, among other sources, a United States military standard MIL-STD-16 which dates back to at least the 1950s in American industry. To replace IEEE 200-1975, ASME, a standards body for mechanical engineers, initiated the new standard ASME Y14.44-2008. This standard, along with IEEE 315-1975, provide the ...

    The following is a list of 7400-series digital logic integrated circuits.In the mid-1960s, the original 7400-series integrated circuits were introduced by Texas Instruments with the prefix "SN" to create the name SN74xx.

  7. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ...

    A capacitive fixed-fixed beam RF MEMS switch, as shown in Fig. 1(a), is in essence a micro-machined capacitor with a moving top electrode, which is the beam. It is generally connected in shunt with the transmission line and used in X- to W-band (77 GHz and 94 GHz) RF MEMS components. An ohmic cantilever RF MEMS switch, as shown in Fig. 1(b), is ...
