Channel calibration re-focuses design approach, but beware complacency
Articles 7/31/2006 Post a comment
In the ancient days of analog signal conditioning and data-acquisition channels, designers put lots of effort into perfecting the input channel. All this has completely changed; it now is easier to accept channel imperfections and calibrate around them. But is's not all "good news"....

Stand-alone differential encoder ICs cut cost, real-estate overheads
Articles 7/27/2006 Post a comment
Product Review - Inphi Corporation's 13650DE and 13651DE, which the company says remain the only stand-alone differential phase shift keying (DPSK) and Duobinary encoders in the industry, are now offered in a QFN plastic package to cut cost and footprint and to provide a measure of compatibility with the company's new 13-series flip flops for use in NRZ applications.
My revised KISS design principle
Articles 7/26/2006 Post a comment
The "Keep It Simple, Stupid" (KISS) engineering design principle gets lots of homage and plaudits, but is often ignored in practice. I'm going to add my two cents to the story and upgrade the KISS principle itself.....

Check out this SMBus to analog interface device that digitizes analog signals for use with digital microprocessors. Microsemi's LX1800 can be paired with its ambient light sensors to incorporate microprocessor-controlled digital dimming of backlight lamps in LCD displays.
Wi-Fi RF front-end chip slashes size, cuts cost
Articles 7/18/2006 Post a comment
Promising to cut system-level integration cost and slash board area requirements, RF semiconductor maker SiGe Semiconductor announces a highly integrated RF front-end module. Slated for Wi-Fi systems compliant with 802.11b/g, the device is very small and eliminates several external discrete components. It packs all functions required between the output of a transceiver and its antenna.

Product Review - Proclaiming a paradigm shift in power supply control techniques with its iW1688 PWM chip, iWatt says it's the first to secure significant benefits from primary-side digital control in low-power AC/DC sources.
Transimpedance amps see more of the photosensor's output
Articles 7/12/2006 Post a comment
MAZeT's second-generation of programmable-gain transimpedance (current-to-voltage) amplifiers, the MTI04CS/CQ, are suited for the company's JenColour photosensor family for evaluating light in tough-to-access environments or where the sensitivity of the human eye is inadequate.
Are engineers foolish?
Articles 7/12/2006 Post a comment
One definition of a fool is someone who does the same thing over and over again, but expects different results. This statement reveals a lack of knowledge of the engineering process by these supposedly smart people, but it is also our own fault....
AM/FM car radio chipset includes data decoder, DSP, embedded ARM7 core
Articles 7/10/2006 Post a comment
Here's news of an FM/AM car radio chipset with on-board DSP and ARM7 processing. It can implement radios that digitally tune current analog radio services worldwide (AM, FM, and weather bands), as well as worldwide digital broadcast modulation schemes such as Digital Audio Broadcasting, Digital Radio Mondiale, and HD radio, where the silicon provides interfaces to external decoders.

ROHM's BU9432-C1 and BU9434-C2 audio system LSIs integrate an MP3 decoder, DAC, system controller, USB host controller, and 3-output power supply to facilitate playback of MP3 files contained in flash memory.
Analog front ends beat a speedy path to integration
Articles 7/6/2006 Post a comment
Product recap - With high-quality front-end processing for data, communications, and imaging systems becoming more critical, designers are fast beating a path to secure analog front ends (AFEs) with higher speed and lower jitter for TV and home theatre applications, better signal conversion topologies for high-definition imaging, higher sensitivity for various wireless authentication systems, greater intersystem compatibility, and faster time-to-market.
The triboelectric effect is defined as a small amount of static electricity generated by the contact and movement of surfaces, used to generate energy that is collected and stored to power sensors and electronics at very low power
The utilization of electronics in medical applications could effectively enhance the quality of life of patients and prevent many cardiovascular distresses: this is confirmed by the result of an observational study, about the CPAP device
This blog series deals with the potential of the utilization of smart electronic ICs in medical care applications; these ICs are produced by companies in the field of semiconductors such as STMicroelectronics which has a broad portfolio of ICs for medical applications
There is rising interest in alternative energy schemes and electric vehicles (EVs) which means there is a growing need in making it possible for power to flow efficiently in both directions.
The industries sector is progressively increasing utilization of IoT technology to make the industrial processes automated in a very intelligent way.
