[introduction] the analogue integrated circuit such as such as amplifier and converter has at least two or two above power source cites a base. To parts of an apparatus of only power source, among them one brings a foot to join normally to the ground. If the mixture signal parts of an apparatus such as ADC and DAC can have voltage of imitate and voltage of digital power source and I/O.   The analogue integrated circuit such as such as…

[introduction] why system of a lot of radio frequency or in the component, a lot of moment are the impedance that uses 50 ohm, how does this numerical value come down certainly, what sense to have rear? The article will open among them mystery for you.   We know the transmission of radio frequency needs aerial and coaxial cable, the transmission of radio frequency signal we always hope to transmit farther distance as far as possible, to transmit farther distance,…

[introduction] compositive and passive parts of an apparatus is not —— of what new thing in our industry their long-standing and well-known. Actually, ADI company ever had produced this kind of component for the market in the past. When compositive perhaps and passive network serves as the schism passive parts of an apparatus that will become independent when chip set to be included inside partly firstly, need gives birth to compatibility of effect, parts of an apparatus and circuit to…

[introduction] Che Jingzhong’s object looks closer than its the real security that this one information is course test and verify warns —— , will a few years warning drivers all the time, the view that rearview mirror place reflects and reality have difference a bit. Although have its limitation, but car lens still is the important equipment on the car, can help a driver turn around or change. However, advanced nowadays drive support system (ADAS) the reflex that surmounted car…
