Conventional wisdom in consumer electronics, driven by Moore's law, calls for increasing functionality on single SoCs. But the laws of physics (heat, current leakage, crosstalk, etc.) have all but eliminated Moore's law as a gating factor for functional integration in consumer electronics. Modern microprocessors drain batteries like the engine of a Hummer drains...
July 21, 2005[Design View / Design Solution] Get More For Less By Using Class D Amplifiers
Decades of development and high-volume production generated mature amplifier technologies that satisfy the requirements of many market segments. Class A designs address more demanding high-end applications, while Class B and AB amplifiers serve the consumer market with cost, power, and performance tradeoffs. Class D technology, however, has changed the balance. With Class D, the power efficiency of audio amplifiers-once constrained to a range roughly between 30% and 50%-has...
