In biomedical engineering specifically gas sensing applications, the concentration of the exhaled gas is converted to a variation in resistance, thus an electronic integrated interface circuit is required to analyze the exhaled gases, which are indications for many diseases. In this paper, a differential resistance to current conversion circuit...

This paper presents a study of Operational Transconductance Amplifiers (OTAs) for voltage to current conversion circuits. The paper includes a comparative analysis of three OTA architectures implemented in 0.35μm CMOS AMS Technology under ± 1.65V power supply voltage. The impact of the OTA topology has been investigated by simulation. The...

Due to their physical principle of operation, resistive gas sensors require very wide range interface circuit. Thus, to design the integrated read out solution, the accuracy in the converted data should be preserved. In this paper, a wide range resistance to current conversion circuit for gas sensing applications is designed. High linear...

In this paper, we present a new version of previously fabricated event driven tactile sensor [1] with modifications across its circuits and methods involved using the AMS CMOS 0.18μm technology. Electrical characterization experimental results are shown and compared to the ones from the previous proving the advantages of the new sensor...
