A 0.5 V 2.5 uW/MHz Microcontroller with Analog-Assisted Adaptive Body Bias PVT Compensation with 3.13nW/kB SRAM Retention in 55nm Deeply-Depleted Channel CMOS
(2019)Microcontroller systems operating at low supply voltage in near or sub-threshold regime suffer both from increased effects of PVT (Process, Voltage, Temperature) variation and from a larger share of leakage on overall power ... -
A 100 kb/s, 4 GHz, 267 mu W Fully Integrated Low Power FM-UWB Transceiver with Multiple Channels
(2018)A 4 GHz, 100 kb/s FM-UWB transceiver for short-range communications in a body area network is presented. Two receivers and a transmitter use the same RF port with a fully-integrated matching network. The first receiver ... -
A 1kb single-side read 6T sub-threshold SRAM in 180 nm with 530 Hz frequency 3.1 nA total current and 2.4 nA leakage at 0.27 V
(2015)A 1kb 180 nm single-side read 6T sub-threshold SRAM has been designed focusing on manufacturability, integrated and measured satisfactorily. Silicon measurements show 3.1 nA total current, 2.4 nA leakage, at 530 Hz for a ... -
A 20 Channel EMG SoC with an Integrated 32b RISC Core for Real-Time Wireless Prosthetic Control
(2019)This work introduces a highly integrated and a power-efficient SoC with 20 EMG sensing channels, a 32b RISC core with a host of peripherals and a companion RF transceiver chip in the 55 nm CMOS technology to enable real-time ... -
A 4-GHz Low-Power, Multi-User Approximate Zero-IF FM-UWB Transceiver for IoT
(2019)This paper presents a 4-GHz FM ultra-wideband (UWB) transceiver designed for the Internet of Things and body area network applications. Robustness to interferers and low power spectral density allow FM-UWB to coexist with ... -
A comparative performance analysis of stand-alone, off-grid solar-powered sodium hypochlorite generators
(2019)Sodium hypochlorite (NaClO) is a chemical commodity widely employed as a disinfection agent in water treatment applications. Its production commonly follows electrochemical routes in an undivided reactor. Powering the ... -
A D-optimal design to model the performances of dressings and devices for negative pressure wound therapy
(2016)A D-optimal design was used to identify and model variables that affect the transit time of wound exudate through an illustrative dressing used for negative pressure wound therapy. Many authors have addressed the clinical ... -
A Kerr polarization controller
(2022-01-19)Kerr-effect-induced changes of the polarization state of light are well known in pulsed laser systems. An example is nonlinear polarization rotation, which is critical to the operation of many types of mode-locked lasers. ... -
A Low-Cost USB-Compatible Electronic Stethoscope Unit for Multi-channel Lung Sound Acquisition
(2020)The diagnosis of respiratory diseases relies largely on auscultation. To further improve the diagnosis quality, continuous acoustic multi-channel surveillance of the airways is highly desirable. The application of multiple ... -
A microphotonic astrocomb
(2019-01)A microphotonic astrocomb is demonstrated via temporal dissipative Kerr solitons in photonic-chip-based silicon nitride microresonators with a precision of 25?cm?s–1 (radial velocity equivalent), useful for Earth-like ... -
A Novel Chewing Detection System Based on PPG, Audio, and Accelerometry
(2017)In the context of dietary management, accurate monitoring of eating habits is receiving increased attention. Wearable sensors, combined with the connectivity and processing of modern smart phones, can be used to robustly ... -
A novel smartphone app for blood pressure measurement: a proof-of-concept study against an arterial catheter
(2022-06-21)Smartphones may provide a highly available access to simplified hypertension screening in environments with limited health care resources. Most studies involving smartphone blood pressure (BP) apps have focused on validation ... -
A passivating contact concept compatible with a short thermal treatment
(2018)In this study we present a boron-doped silicon carbide layers as a hole-selective contact which is compatible with short annealing time (typically < 1 minute) as the one used for firing of metal pastes. The application of ...
