Common-Mode Driven Synchronous Filtering of the Powerline Interference in ECG

open access: yesApplied Sciences, 2022
Powerline interference (PLI) is a major disturbing factor in ground-free biopotential acquisition systems. PLI produces both common-mode and differential input voltages.

Multifrequency bioimpedance device based on the Analog Discovery 2: performance and characterization

open access: yesCurrent Directions in Biomedical Engineering, 2023
Bioimpedance spectroscopy can be used to investigate the composition and monitor the human body, organs, tissues, or cell cultures by measuring the voltage developed by the injection of small alternating currents at different frequencies.

A 0.3 V, Rail-to-Rail, Ultralow-Power, Non-Tailed, Body-Driven, Sub-Threshold Amplifier

open access: yesApplied Sciences, 2021
A novel, inverter-based, fully differential, body-driven, rail-to-rail, input stage topology is proposed in this paper. The input stage exploits a replica bias control loop to set the common mode current and a common mode feed-forward strategy to set its

Finite common-mode rejection in fully differential operational amplifiers

open access: yesElectronics Letters, 2006
A nonlinear mechanism which affects common-mode rejection (CMR) of fully differential integrated operational amplifiers (opamps) is highlighted and analysed by computer simulations. In particular, it is shown how the finite CMR of fully differential opamp circuits under practical operating conditions is mainly related to such a mechanism rather than to

Development of a multistage laser frequency stabilization for an interferometric gravitational-wave detector [PDF]

open access: yes, 2003
Laser frequency stabilization is essential for interferometric gravitational-wave detectors to attain their target sensitivity. We have designed a multistage laser frequency stabilization system which has been applied in the development of the TAMA 300 ...

Low-voltage balanced transconductorwith high input common-mode rejection

open access: yesElectronics Letters, 1994
A balanced transconductor architecture with a high input common-mode (CM) rejection and capable of operating with low supply voltage is proposed. The novel structure is based on a feedforward cancellation of the input CM signal, implemented with an additional transconductor sensitive only to CM signals.

The Beauty of Symmetry: Common-mode rejection filters for high-speed interconnects and balanced microwave circuits [PDF]

open access: yes, 2017
Common-mode rejection filters operating at microwave frequencies have been the subject of intensive research activity in the last decade. These filters are of interest for the suppression of common-mode noise in high-speed digital circuits, where ...

Enhancing common-mode suppression in microstrip differential lines by means of chirped and multi-tuned electromagnetic bandgaps [PDF]

open access: yes, 2016
This article presents common-mode suppressed microstrip differential lines based on chirped electromagnetic bandgaps (EBGs). To achieve common-mode suppression in a wide band, the common-mode impedance is modulated following a sinusoidal chirping ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Differential Bloch Oscillating Transistor Pair

open access: yes, 2013
We examine a Bloch Oscillating Transistor pair as a differential stage for cryogenic low-noise measurements. Using two oppositely biased, nearly symmetric Bloch Oscillating Transistors, we measured the sum and difference signals in the current gain and ...
