Cover Story
- A turn-off: Power management complicates life for verification engineers
Advanced energy-saving techniques can cause vast difficulties in the verification process.
Design Features
- Power-over-Ethernet chips: to the spec and beyond
Power over Ethernet allows a basic Category 5 or 6 cable to carry both data and power, enabling simple and inexpensive installations of equipment such as VOIP phones, cameras, and wireless-access points. - Start with the right op amp when driving SAR ADCs
Using the right operational amplifier in front of your data converter will give you good performance. Adjusting component values by production lot will give you the best performance.
