Abstract

We present an integrated analog signal processor for resource-constrained sensing applications, such as wireless sensor networks, wherein sensors are remotely deployed in inaccessible locations. The processor, which is reconfigurable and operates at 27.8μW, extends the capabilities of sensor nodes by performing spectral analysis and event detection in low-power circuits. The performance of the IC is demonstrated in an example sensing application (i.e. vehicle classification).
