摘要： An amplifier including an amplifier transistor that operates in an active region has main current flowing therethrough according to input voltage, and a linear transistor that is driven by offset positive-polarity input voltage to operate in a linear region and has auxiliary current flowing therethrough. The main current and auxiliary current are added to become output current. The offset positive-polarity voltage corresponds to the sum of AC component of the input voltage and an offset DC voltage. Here, a transistor stacked on the linear transistor is coupled to the amplifier transistor to secure the linear region operation of the linear transistor. The stacked transistor is driven by a voltage having polarity opposite to that of the input voltage.

摘要： An inductor device with a MOS transistor internally installed is disclosed, in which an inductor can be arbitrarily connected in series or in parallel to the respective terminals of MOS transistors by applying a multi-layer wiring technique, thereby reducing the chip area. Within an inductor structure, MOS transistors which have an active region width of W .mu.m are formed in the number of n, and an inductor wire is connected to an arbitrary terminal of the MOS transistors by employing a multi-layer metal wiring process. Thus the inductor is connected to an arbitrary terminal of the MOS transistors in series. Thus an inductor device in which MOS transistors having a channel width of W.times.n .mu.m are internally installed is formed.
