Title: Semiconductor device
Inventor: KAMATA MIKIO
IPC: H01L29/778
Filed: 1984-06-12
Abstract: PURPOSE:To avoid performance degradation and instability attributable to doping by a method wherein a normal-ion FET is easily obtained by using 2DEG to build a channel and adopting a double heterojunction-type construction wherein the two barriers are different from each other in respect of height. CONSTITUTION:A first heterojunction JH1 is formed between a third and second semiconductor layers 3 and 2, and a second heterojunction JH2 is formed between the second and first semiconductors 2 and 1. As for the heights DELTAEC1 and DELTAEC2 of the barriers belonging respectively to the heterojunctions JH1 and JH2, their relationship is expressed by an inequality DELTAEC1<DELTAEC2 when the energy gaps Eg1-Eg3 of the layers 1-3 satisfy an inequality Eg1<Eg3<Eg2. In this DH- MIS-FET7, the second semiconductor layer 2 is thrown into depletion when the device is in operation, when a channel 6 is formed of a 2DEG layer on a side of the second heterojunction JH2 facing the first semiconductor layer 1 or GaAs. In an FET designed as such, electron mobility is enhanced due to the channel 6 of 2DEG in the undoped first semiconductor layer 1, which results in a high-speed FET.

Inventor: KLATSER PAUL
IPC: H03F3/08
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a voltage insulating circuit which uses improved method which combines a HF path(high frequency wave) with a LF path (low frequency wave). SOLUTION: A LF path includes an optical isolator, passes low frequency wave, and performs voltage insulating of input signals. A HF path includes a transformer 102, passes high frequency wave, and performs voltage insulating of input signals. The HF path and the LF path are combined each other in an addition node 104, and insulated input signals are provided. In order to provide flat frequency response, crossover frequencies between the LF path and the HF path must be equal strictly each other. A part of the LF path is inserted in the HF path, and LF component is offset in the region of transient frequency. Thus, by compensating polar frequency of the transformer 102 in the HF path, flat frequency response may be achieved in relation to the combined the LF path and the HF path.
