A New Improved Analog Future

The recent technology revolution has been powered by digital processors. But that’s not the future. “Weird as it sounds, the road to smaller, cheaper, more energy-efficient consumer electronics may be paved with analog technology. These circuits are built from the same components as their digital counterparts but suck 90 percent less battery power. The difference? In an analog device, each transistor acts like a dial, with a wide range of readings that depend on the sinuous fluctuation of voltage, current, amplitude, and frequency. Digital circuits, on the other hand, use the same transistors as simple on-off toggle switches. Analog transistors capture far more information, so you need fewer of them.” Look for the new improved analog at a store near you.
