There seems to be no end to the demand of higher data rate applications and performance requirements as the number of new mobile devices continues to increase dramatically. The usage of mobile devices has evolved from voice only to multimedia messaging, downloading emails, web browsing, online gaming, video calls, social networking etc.
A pop musician recently reminded me that hit songs aren’t only catchy tunes; they are also a barometer of culture. I never expected to refer to Lady Gaga with anything other than casual references to her music or her edgy style (I’ve heard it called “21st-century Madonna), but one of her recent songs gave me some pause.
In March the Associated Press ran a story about security vulnerabilities in smart meters based on the research of InGuardians, Inc. The article highlighted the Achilles heel of any secure wireless system; the inadequate safeguarding of the security keys themselves.
LCD displays are widely used in cell phones, personal media players, internet tablet PCs, laptops, and large-screen TV sets. These displays account for a major part of the power consumed by these devices. For example, a mobile phone screen may consume upwards of 40% of the system power, while in a large-screen TV, the display may consume 70% or more of the system power.
The touchscreen is rapidly becoming the user interface technology of choice in applications ranging from retail, industrial and automotive, to medical, digital signage and gaming. Their growing popularity has been fuelled in part by the phenomenal success of the iPhone and its highly user-friendly, all touchscreen controls...
Despite the potential hazards of ultraviolet light, the UV spectrum is proving to have many beneficial effects in a multitude of areas, offering a wide range of advantages to a diverse number of applications.
Digital video recorders (DVRs) take the analog video input from closed circuit televisions (CCTVs), digitize the input using video decoders and then compress this digital data before storing it on a local storage media like hard disk. The critical advantage that DVRs give over tape-based predecessors is that one can process the recorded data much better and perform event search, time search and more to play back specific content.
As a teenager, I built many "computer" circuits with relays and switches. As I recall, a flip-flop took two 2PDT relays and a binary adder took two 4PDT relays in my brute-force logic circuit. Kids today can get started exploring computers more easily.
Electrocardiogram (ECG) system analog front-end (AFE) devices are typically designed with discrete off-the-shelf components from various semiconductor vendors. The primary components of a traditional discrete ECG AFE include instrumentation amplifiers, operational amplifiers that implement active filters, and analog-to-digital converters (ADCs).
The market for implantable medical devices is estimated at over $40 billion. The recent growth is spurred from significant contributions by the semiconductor industry where new chip technologies revolutionize health care treatments.
The arrival of the iPhone on June 29, 2007 did not just win Apple an overwhelming presence in the personal gadget world, but also changed consumers’ perception of human machine interface forever. The user-driven human touch sensing design is not just intimate with its customers; it is loved.
The newest generation of household appliances and white goods includes more electronics than ever, enabled by innovation and integration in 32-bit microcontrollers (MCUs) along with advances in the always-reliable low-end 8-bit controllers.
This month's question, “What needs to be done for digital power technology to become more accessible to the industry, especially for smaller companies?”, was ansered by Mark Adams of CUI, Chris Young of Intersil, and Rick Zarr of National Semiconductor.
Orthogonal frequency division multiple access (OFDMA) offers many advantages to LTE, notably the ability to deliver high data rates and perform well even in low quality channels. However, the technology does present some difficulties.
Now that the first LTE networks have gone live, the race is on to provide mobile broadband services on a large scale. However, have all the technical issues been addressed?
