1-cc Computer: Cross-Layer Integration with 3.4- nW/bps
Link and 22-cm Locationing

 

Abstract

The first 1-cc computer (OCCC) which integrates a sensor, a wireless transceiver, a computing engine and a battery is demonstrated. Cross-layer innovation includes SPIKE control, which achieves record-low 3.4-nW/bps power with 3-ms UWB current control (one order lower than those of reported). Another proposal is communication-location integration (CLI), which achieves 22-cm location accuracy with 1.3% area overhead. Fabricated OCCC is verified to operate as designed.
