Abstract
A1 . 0m m general-purpose sensor node platform
with heterogeneous multi-layer s tructure is proposed. The sensor
platform bene fits from modularity by allowing the addition/re-
moval of IC layers. A new low power C interface is introduced
for energy ef ficient inter-layer communication with compatibility
to commercial C protocols. A self-adapting power management
unit is proposed for ef ficient battery voltage down conversion for
wide range of battery voltages and load current. The power man-
