Special Issue Information
Dear Colleagues,
High-performance sensing and imaging requires dense integration of the sensor in the circuit environment. CMOS technology is today the most established platform that provides such circuits due to its availability, high density, and low cost. In many cases, the CMOS technology provides the embedded sensing property in the CMOS device itself, while in others, the CMOS circuit provides the sensing front-end and is tightly integrated with the sensing element. Moreover, CMOS integrated circuits provide other functions such as mixed-signal processing, analog to digital conversion, digital processing, and fast signal interfacing.
Image sensors are an outstanding example of circuit and sensor integration. A single CMOS die integrates the full image system from the sensor to the video output. In CMOS imagers, the photons are directly converted into an electrical signal exploiting the light sensitivity of CMOS devices. At other wavelengths, such as in infrared imagers, the light signal may be sensed by a focal plane array that is hybridized to a CMOS readout integrated circuit. Other imagers may be based on the integration of circuits with micro or nanomachined sensors. In addition to imaging, many sensing applications require the integration of a CMOS circuit and sensor. Last but not least, the sensed signal is noisy, and thus, the CMOS circuits are required to provide low noise solutions, particularly at the sensor front-end.
This Special Issue welcomes original papers on the advances of CMOS circuits for sensing or imaging, and from the front-end to the digital output. The CMOS circuit should include characteristics related to the sensing or the imaging process. Some examples are low-noise or micro-power front-end readouts, pixel circuits, parallel image data conversion, and sensor mixed-signal processing.

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.
