Status of Photovoltaic Technology
Last Friday I attended a very informative solar technology workshop put on by the IEEE at Freescale in Austin. It brought together experts in both microelectronics and solar technology who provided a wealth of information about both fields and the … Continue reading
Low-Power Design Has a High-Power Payoff
The New York Times ran a story this morning that speaks directly to engineers involved in low-power design: Plugged-In Age Feeds a Hunger for Electricity. The message and the challenge are clear: “Electricity use from power-hungry gadgets is rising fast … Continue reading
