Special Issue Information

Dear Colleagues,

The development of MEMS toward application in smart sensors is requiring increasingly more compact, high-performance, low-power conditioning architectures especially for IoT and embedded applications. As most of these sensors are resistive or capacitive, this Special Issue focuses primarily on interfaces for this type of sensor. These interfaces can be generic and adaptable to a wide range of nominal values and wide range of full scales of sensor resistance or capacitance. However, specific interfaces are sometimes necessary due to application constraints in terms of resolution, gain, bandwidth, dynamic range, and power consumption.

Original research and review papers are welcome. Topics of interest include, but are not limited to:

  • generic or specific analog front ends for resistive and/or capacitive sensors
  • sensor front ends with direct digital output: R (or C)-to-time conversion, R (or C)-to-frequency conversion, PWM output, ∑Δ output, etc.
  • analog to digital conversion
  • integration in the interface of smart functionalities such as self-test, self-calibration, data fusion, and error correction
  • design methods: automatic tools for sensors’ interface design, co-simulation of sensors and electronics

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

A compact and efficient IC architecture is presented as an alternative to laser-trimmed precision thin-film resistors or look-up tables. The objective is to keep the device, such as a four-terminal Wheatstone bridge, but to compensate for post-manufacturing offset and to avoid the so-induced degradation of performances in terms of full-scale, non-linearity, power supply noise rejection and scale factor. Expected advantages are a reduced cost due to the electrical-only implementation and a possible on-field calibration of high-end sensors. Application of the proposed solution is illustrated on an example to demonstrate improvement factors on offset and sensitivity accuracy of 32 and 10, respectively. Additionally, the power supply rejection ratio is improved by 30 dB. The experimental results finally demonstrate both efficiency and versatility of the proposed solution thanks to a first silicon prototype, fabricated in a 0.35 μm Technology from AMS, connected to an off-the-shelf pressure sensor.
