Patent JP-H1168105-A (JP)
Title: Semiconductor device
Inventor: KUSUNOKI SHIGERU
IPC: H01L21/8242
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the drop of current drive capacity and reduce the switching loss by arranging a constitution such that the width of a depletion layer is narrower than that in the case where a first voltage is applied, or that the depletion layer vanishes, in the case that a second voltage of a gate electrode is applied. SOLUTION: The conductivity type of a gate electrode 12 is different from the conductivity type of a source/drain region. The property of the gate electrode 12, for example, the concentration of impurities is set lower so that the vicinity of the gate insulating film 4 of the gate electrode 12 is depleted in the case that the transistor is off and conversely that this deletion layer is vanishes in on condition. Hereby, in the case that the transistor is off, the thickness of the gate insulating film becomes thick by the depletion layer produced in the gate electrode 12, which can cut off the current with a high threshold voltage. When the transistor is on, an electric field is generated in the region 10 from the gate electrode 12, so that an inversion layer can be made within the channel, and high current drive force can be obtained.

Title: Output amplifier circuit
Inventor: TAYA TAKASHI
IPC: H03F3/45
Filed: 1987-09-16
Abstract: PURPOSE:To obtain a circuit highly insulated against an abnormal voltage impressed to an output terminal by giving a current being the subtraction of a 1st output current from a 2nd output current by a current arithmetic means to an input of a common collector amplifier circuit so as to suppress a change in an output impedance thereby suppressing the production of distortion. CONSTITUTION:The current arithmetic means gives a current being the subtrac tion of the 2nd output current I02 from the 1st output current I01 of a differential amplifier circuit to the input of the common emitter amplifier circuit. Moreover, the current arithmetic means gives a current being the subtraction of the 1st output current I01 from the 2nd output current I02 of the differential amplifier circuit to the input of a common collector amplifier circuit. Then the power proportional to the input voltage is supplied to a load connected to an output terminal T3 via the common emitter amplifier circuit and the common collector amplifier circuit. Thus, the fluctuation of the output impedance against the load is suppressed and the output amplifier circuit with high fidelity and immune to an abnormal voltage is formed.
