Demystifying the A/D and D/A Converters

Analog and Digital Signals Analog signals represent a physical parameter in the form of a continuous signal. In contrast, digital signals are discrete time signals formed by digital modulation. Most natural signals, like human voice and other sounds are analog in nature. Traditionally, communication systems were based on analog systems. As demand for systems capable of carrying more information over longer distances kept soaring, the drawbacks of analog communication systems became increasingly Read more [...]

Microchips to be imbedded in pills?

Yes, it's true. Proteus Biomedical has announced that they will be launching a innovative product that imbeds microchips in pills so that patients can be monitored by their health care professionals and even their families. The purpose of the monitoring is to be sure that patients are taking their medications properly and on time and to also monitor a range of additional patient information including respiration rate, heart rate, temperature, sleep patterns and physical activity. It is estimated Read more [...]

Google Doodle Honors Robert Noyce – “Mayor of Silicon Valley”

Robert Noyce is being honored by Google for his contributions to the electronic components industry on what would have been his 84th birthday. To commemorate his birthday, Google's homepage has a doodle which etches the Google logo onto a microchip, a technology that Noyce is credited with co-inventing. Known as the Mayor of Silicon Valley, Robert Noyce was the co-founder of Fairchild Semiconductor and Intel and is credited along with Jack Kilby with the invention of the integrated circuit.

Available Methods of Marking Semiconductors

Semiconductor Markings - Available Methods Traditionally, most components have two or three lines of identifying marks plus a company logo. Over time, the manufacturer codes have become more involved to incorporate a component's identification plus the complete history of the process. Early on, it was the military applications that required very specific markings and identification processes. Current package markings are a by-product of those military requirements. When a semiconductor is clearly Read more [...]

Op Amps – Then and Now

Op Amps – Then and Now Op amp is the commonly used name for operational amplifiers, which are widely used electronic components. Op amps are often seen on many surface equipment designs and logging tools. The name ‘operational amplifier’ comes from the use of such high gain amps in performing mathematical operations for analog computer operations and is said to have been coined in 1947. A lot of study was done in the field and the initial operational amplifiers, based on Read more [...]
