The rapid advance of CMOS technology has been primarily geared towards optimizing the performance of digital circuits. As a result, analog CMOS circuits not only continue to lose the benefit of specialized components, they must also cope with a rapidly shrinking voltage headroom, worsening device mismatch, and deteriorating linearity while satisfying ever stringent specifications. Time-based signal processing, where analog information is represented by the time difference between the occurrence of two digital events, offers a viable and technology friendly means to combat difficulties encountered in design of mixed analog-digital systems. Time-based signal processing deals with the addition, subtraction, multiplication, amplification, differentiation, integration, quantization, etc., of time variables. Time-mode circuits possess the full merits of digital circuits including fully compatibility with technology scaling, programmability, portability, immunity to disturbances and noise, and a short design cycle that which are not possessed by their analog counterparts. Time-based signal processing has found a broad spectrum of emerging applications in including vehicle navigation systems, data converters, finite and infinite impulse response filters (FIR, IIR filters), all digital phase-locked loops and frequency synthesizers, and high-speed data links, to name a few. This Special Issue is aimed at presenting the latest research findings in time-based approaches for mixed-mode signal processing. Topics of interest include voltage-to-time converters, time-to-voltage converters, time-to-digital converters, digital-to-time converters, time-mode arithmetic circuits such as time adders, time differentiators, and time integrators, time registers, time quantizers, time amplifiers, time-mode delta-sigma modulators, time-mode successive approximation register analog-to-digital converters, time-mode all-digital phase-locked loops and frequency synthesizers, time-mode FIR and IIR filters, and time-mode data links.

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. Journal of Low Power Electronics and Applications is an international peer-reviewed open access quarterly 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 1800 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.
