Let the ultrasound imaging quality taller, lower power consumption (1)

Ultrasound platform of imaging quality and system power consumption, always been vary in "zero-sum game", especially for portable devices.

As early as in April 2007, ADI has launched the world's first integrated 8 channel in AD9271 microchip — but an year and a half later, for some of the more high-end applications, the chip appeared to be in power on "powerless."

This time came into being higher performance, lower-power chips also became inevitable.

"The industry has been looking forward to these two chips," ADI greater China Senior Business Manager Zhou Wen sheng on electronic engineering world.

Actually, this is two kind of chips?

A true "single"

Talk about the latest two eight-channel ultrasonic receiver AD9272, Paul Sheng AD9273, prefer to be described as a true "single solution".

Together with the previous AD9271, AD927x products use integrates eight-channel single-chip replaces the previous discrete solutions, each channel contains a low noise amplifier (LNA), a variable gain amplifier (VGA), an anti-aliasing filter (AAF) and a 12-bit analog-digital converter (ADC).

"Compared with digital technology, simulation technology more rely on accumulation," says Paul is better.

From previous discrete programmes to "single" programme, to today's from AD9271 AD9273, AD9273, seemingly simulation product features are only a small step forward, in fact there are quite a lot of technology background. Of these, the most valuable, and it is precisely this ADI has some accumulation of old engineer: when the company was founded in ADI working them, now 60 or 70 years old and still working for the ADI, they even can clap CEO shoulders feel free to chat. At the same time as the transfer of product platform, more and more companies to programmes, ADI has increased a lot of system integration engineer, who also became the core of ADI market share.

And ADI in FY 2007 sales, compared to $ 24.3 medical electronic share of about 5%, and the traditional advantages of the Terminal market industrial and instrumentation, consumer electronics, wireless infrastructure and not a very big compared to.

But the average annual growth of 18% still makes people shall not be underestimated. At the same time, medical electronics has also been many businesses as secondary PC, mobile phone after the next round of competition.

Conventional medical electronics field, can be divided into 5 parts: Imaging, patient monitoring, instrumentation, consumer and implants.

Which medical imaging including CT, ultrasound, digital x-ray, MRI, currently the world's most popular is the ultrasonic and digital x-ray (2000 basic analog x-ray machines, this digital faster). While the current domestic production CT vendor less familiar is the GE, Neusoft. While MRI in domestic is not a very mature. While most of the medical business ADI are based on medical imaging systems.

Patient care category more refers to ECG machine, Pulse Oximeter, ventilator and automated external defibrillator.

For example, high-risk patients need to take your Pulse Oximeter with GPS functionality, you can reference the location of the patient, if a problem occurs, you can pass the recent rescue centre where patients.

The main instrument is the analysis.

If the blood analysis, urine analysis, etc.

The remaining two parts of the consumer and embedded devices, ADI now do less, but also very concerned about.

In the past ten to twenty years, consumer products in Europe and more popular, glucose monitor, ear thermometers and blood pressure and heart rate monitor for all products belonging to this class. Implantable devices in general are integrated small system, it can detect your blood sugar concentrations, when the concentration is greater than a certain amount of time needed to release the drug, the drug has been implanted into your body, then it will stimulate the release of the drug, this technology has not yet, but already very popular abroad.
