Special Issue Information

Dear Colleagues,

Implantable integrated circuits have long been utilized in a variety of biomedical applications, such as pacemakers and coclear implants. These devices have had a significant success and impact on human health care. Future implants will have the more ambitious goals of observing brain activity, decoding the extracted neural information, and, ultimately, restoring disabled functionality to the body. These next generation implantable ICs, which will interface with the nervous system, will be extremely helpful in better understanding neural pathways and the etiology of neurological diseases.

This special issue will focus on the design, testing, and application of bio-implantable ICs. Papers on IC design with application to brain recording and stimulation are particularly encouraged.

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.

An ultra-low-voltage low-power switched-capacitor (SC) delta-sigma (ΔΣ) modulator running at a supply voltage as low as 300 mV is presented for biomedical implant devices, e.g., cardiac pacemakers. To reduce the supply voltage, an inverter-based amplifier is used in the integrators, whose DC gain and gain-bandwidth (GBW) are boosted by a simple current-mirror output stage. The full input-feedforward loop topology offers low integrators internal swing, supporting ultra-low-voltage operation. To demonstrate the concept, a second-order loop topology was chosen. The entire modulator operates reliably against process, voltage and temperature (PVT) variations from a 300 mV ± 10% supply voltage only, while the switches are driven by a charge pump clock boosting scheme. Designed in a 65 nm CMOS technology and clocked at 256 kHz, the simulation results show that the modulator can achieve a 64.4 dB signal-to-noise ratio (SNR) and a 60.7 dB signal-to-noise and distortion ratio (SNDR) over a 1.0 kHz signal bandwidth while consuming 0.85 μW of power.
