Design of a low voltage 0.18 um CMOS Surface Acoustic Wave gas sensor
A Surface Acoustic Wave (SAW) gas sensor is designed and tested in this paper. The objective of the designed SAW Gas sensor is to detect H2S and NOX gases. The inter-digital transducers (IDT) antennas in the proposed sensor are coated with thin film WO3, which mass is sensitive to mentioned gas conc...
