Startup Offers Peltier-On-Chip
LowSNR writes "The South Carolina based startup Nextreme, Inc. is developing technology to put Peltier Coolers in chip packages, according to an Ars Technica report. The tiny coolers could be situated on top of local hotspots on the die and pump heat away through a package pin to the motherboard. Also, the Seebeck Effect allows the waste heat to be used to be harvested to generate/reclaim power."
Peltier devices on-chip have been used for a while, whenever temperature variations are intolerable. Some examples: Analog Devices AD595 thermocouple amp, which uses in-chip thermal calibration to ensure a cold junction of known temperature, and many voltage regulators and switching supply controllers that use temperature-controlled bandgaps as their voltage reference.
Nostalgia's not what it used to be.
