Silence is golden in power design

摘要

With the vast uptake in portable connectivity devices and the ever shorter design cycles, competition is fierce. The noise performance of the power supply is vital and needs to be of extreme importance for designers of these new sensitive products. One of the greatest challenges for engineers in achieving high performance in their designs is that of the cleanliness of the supply rails. Traditional power design processes for global positioning systems (GPS), cellular phones and image sensors are simply not good enough for the performance levels required today.
