Transistor Linear

what is meant by linear operation of a transistor?

difference between transistor at low and high frequencies

Linear operation means the transistor is neither saturated, nor cut-off. It is operating in the range of Vce and Ic where it acts as an amplifier and not a switch.

For low and high frequencies, usually different models are used, or… the same low frequency model is used and capacitors are included in the model when it is used for high frequencies.

Advances in manufacturing techniques at sub-micron and micron IC manufacturing allows more number of transistors every inch silicon square. Extensive research was also done in the optical and magnetic storage. The digital 1s and 0s are stored by the metal particles. As time passed, the size of metal particles is increasingly young and then fell to nanosecond. These changes to store more bits and more storage means every square inch. Density area also known as the bit density is the key to fuel development Information Technology.

Data recording has many parameters needed, but two of the most important magnetic properties of remanence and coercivity. Proportion of the company to noise is controlled by the remanence that helps reliably read digital 0s and 1s. Areal density is governed by the coercivity that increase the capacity of each area of the tape recording of data. From the magnetic energy of the film is the product of these two numbers. The most important advantage of the density area is that it increases the recording capacity. High recording density results in greater efficiency and output as file transfer moves less than last tape reel tape heads.

LTO tape format has all the powerful features that provide reliable backup solutions. LTO tape cartridge can hold more data on the volume, due to its high density recording so that the time taken to change the tape cartridge is also reduced. By restoring data on LTO Ultrium tape format is very fast. The data restore process is accelerated by the faster access and restoration LTO technology. Therefore, organizations can save lots of money with the help of fast food technology LTO tape format. The length of the LTO-3 tape cartridge is 680 meters and the LTO-4 tape is 820 meters. The LTO4 cartridge size is not increased. So it became thinner tape spool (6.6 micrometers) in LTO-4 tape cartridge of 8.0 micrometers used in the LTO 3 tape cartridge.

So the base film of the LTO-4 should be more stronger and harder, as LTO4 tape drives were small read / write head. Sony uses the base film polymer alloy hybrid to solve this problem. Lateral resistance of the Sony LTO-4 tape is increased by 45 percent and size changes are reduced by 60 percent by the use of polymer film alloy. There may be some differences among the remains of reel of tape and tape head that can lead to errors and degraded performance. If the base film is weak, spacing is more likely gaps. Film base polymer alloy Sony LTO4 tape prevents the spacing of the gaps to improve production performance and LTO4 tape technology. Servo track in Sony LTO4 data tape is ultra precise.

As data tracks used in LTO-4 are 896 in comparison with the LTO-3 data tracks 704, so it is very important that the recorded tracks and recording / playback tape head must be correctly aligned. On the tape, the tracks are written previously, part of the manufacturing procedure. Vast and extensive experience in media and hardware manufacturing helped Sony in the technology development servo-track recording. In this technology, the servo tracks are kept small width tolerance of 0.14 percent. This technology in Sony LTO 4 tape allows remarkable accuracy in both reading and writing.
