miniature electronic
Tuesday, August 16th, 2011The integrated circuit (integrated circuit) is one kind of miniature electronic device or the part. Uses certain craft, needs parts and the wiring interconnection same place and so on transistor, diode, resistance, electric capacity and inductance an electric circuit, manufactures in a scrap either on several scrap semiconductor chip or the medium substrate, then the seal in a shell, becomes has needs the electric circuit function the miniature structure;
And all parts have composed a whole in the structure, caused the electronic component to turn toward the microminiature, the low power loss and the redundant reliable aspect made great strides forward a stride. It “IC” expressed in the electric circuit with the letter.cool wisdom
The integrated circuit inventor (based on silicon integrated circuit) and Robert · Noy thinks for Jake · Killby (based on germanium integrated circuit). What now the semiconductor industry majority applies is based on the silicon integrated circuit.
The integrated circuit has the volume to be small, the weight is light, the lead-out wire and the weld point are few, the life is long, the reliability is high, performance good and so on merits, simultaneously the cost is low, is advantageous for the large scale production.
It not only in the labor, civil aspects and so on electronic installation like radio cassette player, television, computer obtains the widespread application,capacity classification
simultaneously in aspects and so on military, communication, remote control also obtains the widespread application. Assembles the electronic installation with the integrated circuit, its packaging density may enhance several dozens times to several thousand times compared to the transistor, equipment’s steady work time may also enhance greatly.
The integrated circuit according to its function,WHITE QUARTZITE
the structure difference, may divide into the simulation integrated circuit, the digital integrated circuit and the number/mold hybrid integrated circuit three major market days becomes the electric circuit class.
The simulation integrated circuit calls the linear circuit, uses for to have, to enlarge and processes each kind of simulated signal (to refer to the scope along with the time variation signal. For example transistor radio’s tonic train signaling, the recording and sending out machine magnetic tape signal and so on), its input signal and the output signal become the proportional relationship. But the digital integrated circuit uses for to produce, to enlarge and processes each kind of digital signal (to refer to the time and the scope is separated the value the signal.
For example 3G handset, digital camera, computer CPU, digital television’s logical control and replay tonic train signaling and video signal).
The integrated circuit may divide into the double pole integrated circuit and the single pole integrated circuit according to the conduction type, they are the digital integrated circuits.
The double pole integrated circuit’s production process is complex, the power loss is big, has types and so on TTL, ECL, HTL, LST-TL,hotel interior design STTL on behalf of the integrated circuit. The single pole integrated circuit’s production process is simple, the power loss is also low, easy to make the large scale integrated circuit, has types and so on CMOS, NMOS, PMOS on behalf of the integrated circuit.
