Talk: mm-Wave Ultra-Low-Power Wireless Sensing

On Oct. 11th Dr. Hao Gao (Eindhoven University of Technology) was invited to talk about the highly innovative topic of mm-Wave Ultra-Low-Power Wireless Sensing at JKU Linz. In particular, he focused on mm-Wave transceiver capabilites to guarantee power autonomous sensor nodes. The talk was jointly organized by Silicon Austria Labs, JKU Linz and IEEE Austria CAS/SSC Joint Chapter.

Sensor nodes autonomous from power-supply

Millimeter-Wave (mm-wave) wireless communication provides several GHz ISM bandwidth using high data rate communication in short bursts with high duty-cycle for lowest power systems. Combined with an on-chip wireless power receiving technique, an on-chip antenna, a fully integrated monolithic passive mm-wave sensor node for internet of things (IoT) can be realized. Such a sensor node is autonomous from an external power-supply, as well it can sense the environment, receive commands and transfer the sensing information.

How to overcome the bottleneck of power consumption for mm-wave circuits

In order to overcome the challenge of the power consumption of mm-wave circuits for achieving monolithic passive sensor nodes, Hao Gao focuses on transceiver architectures and RF circuit techniques. He especially pointed out the demand of smart circuit solutions to enable power-autonomous wireless systems for IoT applications focusing on the harvester circuits and receiver architectures and implementations employing integrated antennas for 60GHz wireless operation for smallest possible sensor nodes.
