Computer system

Abstract

The invention relates to a computer system which comprises an information acquisition unit, a signal amplification circuit and a central processing unit. The output end of the information acquisitionunit is connected with the input end of the signal amplification circuit, and the output end of the signal amplification circuit is connected with the input end of the central processing unit. The signal amplification circuit comprises a transistor, wherein the transistor adopts a self-bias mode to enable the transistor to work in a conduction state so as to amplify signals acquired by the signalacquisition circuit; the transistor comprises a substrate of a first conductivity type, a first epitaxial layer of a second conductivity type formed on the first surface of the substrate, a second epitaxial layer formed on the upper surface of the first epitaxial layer, isolation regions, an emitting electrode, a base electrode and a collector electrode, wherein the isolation regions are formed onthe two sides of the second epitaxial layer, and one end of each isolation region penetrates through the second epitaxial layer and the first epitaxial layer and then extends into the substrate.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a computer system. Background technique [0002] In today's era of rapid technological development, computer systems, such as desktop computers, notebook computers, tablet computers, etc., have been widely accepted by people, and have gradually become an important platform for people's work and entertainment. The computer system collects the operating status or input information of the load or external input devices in real time through multiple acquisition devices, and then amplifies the collected weak signals through the amplification circuit and then sends them to the central processor for processing, so as to realize the monitoring of each hardware device. monitoring. In the prior art, a transistor is a commonly used core component of an amplifier, and the instability of its amplification factor often affects the working efficiency of the entire computer system.
