Special Issue Information

Dear Colleagues,

ADCs and DACs are widely used in various signal-processing systems. With the increasing demand of ADCs and DACs in IoT, sensing, communication and controlling applications, the energy efficiency, sampling rate and conversion accuracy are required to be co-optimized.

This Special Issue seeks high-quality contributions that address latent challenges in ADCs and DACs with different architectures and contribute to the advancement of the state of the art in this field. Research papers detailing theoretical and experimental developments are welcome. The topics of interest include, but are not limited to, the following:

  1. High-resolution noise-shaping related ADC (NS SAR ADC, ∑Δ ADC, zoom ADC);
  2. High-resolution Nyquist ADC (the ENOB generally is no lower than 16 bits);
  3. High-speed ADCs, including both single-channel and TI types;
  4. Energy-efficient ADCs with the FoM result achieving the state-of-the-art level;
  5. High-performance analog circuits employing ADCs and DACs.

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. Electronics 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 2400 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.

This article is devoted to the development of a new method of logarithmic analogue-to-digital conversion using switched capacitors with a variable logarithmic base. The essence of the method and its implementation are presented. Mathematical models have been developed, analysis has been carried out and errors have been assessed. It has been demonstrated that the developed converters, using the proposed method, significantly outperform known analogous converters: for input voltages ranging from 1 mV to 10 V, the processing error does not exceed 0.001% with a processing time not greater than 105 µs (microseconds).

This paper presents a digital calibration method for a 10-bit noise-shaping Successive Approximation Register Analog to Digital Converter (SAR ADC). The proposed calibration method is inspired by its Data Weight Averaging (DWA) counterpart, but stays static, while achieving a similar Integral Nonlinearity (INL) and 1.3 dB better Signal-to-Noise Ratio (SNR) in measurements without oversampling. This advantage in SNR holds until an Oversampling Ratio (OSR) of 2 for the proposed method, which also saves 50 % power. At a 1.2 V power supply, the ADC consumes a power of 70 µW at a conversion rate of 50 kHz. Fabricated using 55 nm Complementary Metal Oxide Semiconductor (CMOS) Metal-Oxide-Metal Capacitor (MOMCAP) technology, it occupies an active area of 370 µm × 350 µm, when achieving an INL of 0.3 Least Significant Bit (LSB) and an SNR of 66.9 dB at an OSR of 8.
