The National University of Singapore and Politecnico di Torino teamed up at ISSCC 2021 to describe a capacitive sensor interface designed to run from harvested energy, needing only a supply voltage between 300mV and 1.8V to produce an output accurate to seven bits, and consuming 1.4nJ per conversion. Not only that, but it needs no ...
