    Miller Electric is an American arc welding and cutting equipment manufacturing company based in Appleton, Wisconsin. Miller Electric, has grown from a one-man operation selling products in northeastern Wisconsin to what is today one of the world's largest manufacturers of arc welding and cutting equipment.

  3. Miller effect - Wikipedia

    en.wikipedia.org/wiki/Miller_effect

    In analog amplifiers this curtailment of frequency response is a major implication of the Miller effect. In this example, the frequency ω 3dB such that ω 3dB C M R A = 1 marks the end of the low-frequency response region and sets the bandwidth or cutoff frequency of the amplifier.

    en.wikipedia.org/wiki/Eico

    EICO is also known for "monoblock" amplifiers such as the HF-50 and HF-35, stereo integrated amplifiers such as the ST-40 and ST-70, as well as many other amplifiers and preamplifiers. In the late 1960s, EICO introduced a line of solid state electronics audio equipment referred to as Cortina , but by the mid-1970s the only audio products they ...

    en.wikipedia.org/wiki/Cascode

    The use of a cascode (sometimes verbified to cascoding) is a common technique for improving analog circuit performance, applicable to both vacuum tubes and transistors.The name "cascode" was coined in an article written by Frederick Vinton Hunt and Roger Wayne Hickman in 1939, in a discussion on the application of voltage stabilizers.

  7. Charge amplifier - Wikipedia

    en.wikipedia.org/wiki/Charge_amplifier

    Charge amplifier for piezoelectric sensors. Practical charge amplifiers usually include additional stages like voltage amplifiers, transducer sensitivity adjustment, high and low pass filters, integrators and level monitoring circuits. The charge signals at the input of a charge amplifier can be as low as some fC (FemtoCoulomb = 10 −15 C). A ...
