噪声从便携式系统设计的角度分析将帮助您在电源设计中作出适当的权衡。Maxim > App Notes > BATTERY MANAGEMENT POWER-SUPPLY CIRCUITS Keywords: Circuit Tradeoffs Minimize Noise in Battery-Input Power Supplies Jan 22, 2001 APPLICATION NOTE 653 Circuit Tradeoffs Minimize Noise in Battery-Input Power Supplies Analyzing noise from the perspective of portable-system design will help you in making appropriate trade-off in power-supply design. RF-communicating computers and other new mobile systems can act as portable generators of unwanted noise and EMI, thereby hampering their own market acceptance. Witness the near disaster at New York's La Guardia Airport, in which EMI from a notebook computer may have caused a failure in an airliner's landing system.
