Title: Power amplifier of less phase distortion
Inventor: HAYASHI HITOSHI
IPC: H03F3/24
Filed: 1994-09-13
Abstract: PURPOSE: To cancel the phase distortion in the whole of a power amplifier by connecting an opposite phase distortion generator using a drain grounded FET to the preceding stage of an amplifier using a source grounded FET. CONSTITUTION: An opposite phase distortion generator 13 using a drain grounded FET 20 is connected to the preceding stage of an amplifier 14 using a source grounded FET 25. Generally, the gain is reduced in accordance with the increase of input power and is changed in the advancing direction of the output phase in the amplifier using the source grounded FET. Meanwhile, the gain is reduced in accordance with the increase of input power and is changed in the delaying direction of the output phase in the amplifier using the drain grounded FET. Consequently, the opposite phase distortion generator 13 using the drain grounded FET 20 and the amplifier 14 using the source grounded FET 25 are combined and the operation point in each stage is optimized to compensate the phase distortion in the whole of the power amplifier.  Since FETs functioning as amplifiers are combined, the power efficiency is high and the power amplifier is easily made into a monolithic IC.

Abstract: PURPOSE:To reduce a parasitic capacity generated upon formation of an electrode for bonding thereby to improve high frequency characteristic by forming a structure that a part of a dielectric film under the electrode is removed. CONSTITUTION:An electrode 7 for bonding and a dielectric film 3 are partially contacted to form a space 8.

At this time, the area of the electrode 7 can remain as the conventional one, and the bondability is not lost. Accordingly, the assembling easiness remains as the conventional one and the parasitic resistance is reduced to improve the breaking frequency and high frequency characteristics.
