Autor: Yusaku Hirai, Toshimasa Matsuoka, Sadahiro Tani, Shodai Isami, Keiji Tatsumi, Masayuki Ueda, Takatsugu Kamata
Publikováno v: IEEE Access, Vol 7, Pp 21990-22001 (2019)
This paper presents a high-precision biomedical sensor system with a novel analog-frontend (AFE) IC and error correction by machine learning. The AFE IC embeds an analog-to-digital converter (ADC) architecture called successive stochastic approximati

A Software Level Calibration Based on Bayesian Regression for a Successive Stochastic Approximation Analog-to-Digital Converter System
Autor: Toshimasa Matsuoka, Keiji Tatsumi
Publikováno v: IEEE Transactions on Cybernetics. 49:1200-1211
Recently, a novel low-power high-precision analog-to-digital converter (ADC) called the successive stochastic approximation ADC has been proposed which has two kinds of outputs from different modes, and which requires a software-level error correctio

Behavior-Level Analysis of a Successive Stochastic Approximation Analog-to-Digital Conversion System for Multi-Channel Biomedical Data Acquisition
Autor: Toshimasa Matsuoka, Toshifumi Kurata, Masayuki Ueda, Keiji Tatsumi, Sadahiro Tani, Takatsugu Kamata, Yusaku Hirai, Tomohiro Asano
Publikováno v: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences. :2073-2085
In the present paper, we propose a novel high-resolution analog-to-digital converter (ADC) for low-power biomedical analog frontends, which we call the successive stochastic approximation ADC. The proposed ADC uses a stochastic flash ADC (SF-ADC) to

Yabuuchi, Toshimasa Matsuoka, Mabel Ruiz-Lopez, Davide Bleiner, Sergei Pikuz, Y Ochante, Makina Yabashi, Norimasa Ozaki, A. Faenov, T. A. Pikuz
Publikováno v: Journal of Synchrotron Radiation. 24:196-204
Direct metrology of coherent short-wavelength beamlines is important for obtaining operational beam characteristics at the experimental site. However, since beam-time limitation imposes fast metrology procedures, a multi-parametric metrology from as

A Design of 0.7-V 400-MHz All-Digital Phase-Locked Loop for Implantable Biomedical Devices
Autor: Weimin Wang, Saichandrateja Radhapuram, Takao Kihara, Jungnam Bae, Ikkyun Jo, Toshimasa Matsuoka
Publikováno v: IEICE TRANSACTIONS on Electronics. (4):431-439
A low-voltage controller-based all-digital phase-locked loop (ADPLL) utilized in the medical implant communication service (MICS) frequency band was designed in this study. In the proposed design, controller-based loop topology is used to control the

Publikováno v: IEICE Electronics Express. 13(6):1-10
A new non-linearity reduction technique for stochastic flash ADC (SF-ADC) is proposed, focusing on distribution of comparator input-referred offsets. The SF-ADC test chip fabricated in a 130-nm CMOS process demonstrated the proposed technique can imp
