Research On The Mobile Communications Market Competition And The Improvement Of The Quality Of Service

Nowdays, the processor and computer system are developing moreand more complex. The current measurement is taking an importantrole compared with general design process, which is necessary trend forelectrical industry. The trend of electrical industry is to provide moreportable and functional. It is widely used in all kinds of portable electricalinstruments and consumer electronic equipments. Per current point, it isimportant to the current test design.The development of it technology combination with others lead toportable product development. Portable product is termination of newdigital multimedia. This becomes especially important in the case ofhandheld devices, cellular phones etc. The most important features ofmobile device design is low power consumption. With scaling ofprocesses there is an increased need for decreasing the current drawn bythe digital logic of chips. Competition is more and more intensely, thenew technology will come forth. It lead to new development of newportable terminal and relevant equipment emergency, which bring a bigchallenge. The advantage of reducing current is increased battery life.This becomes especially important in the case of handheld devices,cellular phones etc. The most important features of mobile device designis low power consumption.The i.mx35high performance processor which was provided byfreescale semiconductor has high level specification for current test.Current measured in different condition which ic has been set to differentmode. The current measurement data will be different when ic set todifferent mode. This paper based on a comprehensive introduction of thecurrent measurement structure and principle. Meanwhile, this paperfocuses on current limits specification. Reset the current limit based onthe customer application so that the theoretic current limit accord toactual limit.
