| LED lamps will replace light bulbs in near future |
| 2008-05-11 16:24:17 |
Seems this can be true. Faiz Rahman who is a nano electronics researcher at Glazgow university states that low-energy bright LED light Bulbs are almost here. As matter of fact LEDs are very energy efficient, but fact is that about 70% of electrical energy is converted to light, and only about 20% of it getting [...]...

| Voltage references in embedded design |
| 2008-05-08 16:21:17 |
Embedded systems that are dealing with DAC require a good voltage references. Despite all voltage references have their nominal values there are specific tolerances that indicates how much values can vary from nominal value. References as a rule are semiconductors that characteristics are effected by temperature.
For instance if we decide to use a 2.5V voltage [...]...
