Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to provide a comprehensive overview of integrated circuits and systems for smart sensing applications. Research articles and reviews are sought that provide insight into any aspect of integrated circuits and systems for smart sensing applications. Topics of interest include, but are not limited to, the following:

  • Temperature and pressure sensors for biomedical application;
  • Sensors and interfaces;
  • Energy harverster circuits;
  • Power management circuits;
  • Signal adaptation and conversion circuits;
  • Voltage and power management for integrated sensors;
  • Analog, mixed-signal, and digital signal processing blocks;
  • Time and frequency domain readout circuits;
  • Digital signal processing for sensors;
  • Wireless and wireline data transceivers.

In this article, a novel front-end circuit for remote two-wire resistive sensors that is insensitive to the wire resistances is proposed and experimentally characterized. The circuit relies on an OpAmp-based current source with a square-wave excitation, two twin diodes in the feedback path, and a low-pass filter at the output. Using such a circuit topology, the output is a DC voltage proportional to the sensor resistance and independent of the wire resistances. A prototype was built measuring resistances that correspond to a Pt100 thermal sensor and with different values of wire resistance. The experimental results show that the output voltage is almost insensitive to both the wire resistances and their mismatch, with a relative error (with respect to the case with null parasitic resistance) in the range of 0.01–0.03% Full-Scale Span (FSS). In addition, the proposed circuit shows a remarkable linearity (around 0.01% FSS), and again this is independent of the presence and also of the mismatch of the wire resistances. Full article
