    摘要: Inductors used for impedance matching in the radio frequency integrated circuits is disclosed. In the integrated inductor device according to the present invention, an additional electrode is arranged in surroundings of an inductor metal line, and the reverse bias voltage is applied to the region between the substrate and the electrode so as to form a depletion layer. Therefore, the substrate biasing is effected and thus an inductor having improved performance can be formed by decreasing the parasitic capacitance between the inductor metal line and the substrate. The present invention can also be applied to another semiconductor device having metal lines and pads.

    摘要: Electronic devices with a VCOM display panel are configured to provide a common voltage VCOM to a VCOM display panel backplane, referred to as a VCOM reference plane. The common voltage is supplied by a VCOM application circuit coupled to the VCOM reference plane. The VCOM application circuit includes a linear amplifier, such as a Class AB amplifier, coupled to a switched transient assist circuit configured to output the common voltage. The switched transient assist circuit stabilizes the amplifier in the presence of large transient output currents but with minimized power dissipation and heat rise in the amplifier.
