Wall Repulsion during Electrophoresis: Testing the Theory of Concentration-Polarization Electroosmosis
(AIP Publishing, 2023)
We experimentally study the repulsion of charged microscopic particles with the channel walls during electrophoresis in microfluidic devices. For low frequencies of the electric fields (< 10 kHz), this repulsion is mainly ...

Scattering of Metal Colloids by a Circular Post under Electric Fields
(MDPI, 2023)
We consider the scattering of metal colloids in aqueous solutions by an insulating circular post under the action of an AC electric field. We analyze the effects on the particle of several forces of electrical origin: the ...

On the Use of FIR Feedback in Bandpass Delta-Sigma Modulators
(IEEE, 2024-03)
This paper presents a new architecture for bandpass delta-sigma modulators (BP ΔΣ Ms) featuring finite impulse response (FIR) filters in the feedback path. The effectiveness of FIR feedback in lowpass delta-sigma modulators ...

Reducing the nonlinearity and harmonic distortion in FD-SOI CMOS current-starved inverters and VCROs
(Elsevier, 2021)
This paper demonstrates experimentally how to reduce the nonlinearity of some analog and mixed-signal circuits by using the enhanced body effect provided by Fully-Depleted Silicon on Insulator (FD-SOI) CMOS technology. A ...

A CMOL-Like Memristor-CMOS Neuromorphic Chip-Core Demonstrating Stochastic Binary STDP
(Institute of Electrical and Electronics Engineers Inc., 2022-12)
The advent of nanoscale memristors raised hopes of being able to build CMOL (CMOS/nanowire/molecular) type ultra-dense in-memory-computing circuit architectures. In CMOL, nanoscale memristors would be fabricated at the ...

Design of Broadband Aperture-Coupled Stacked Microstrip Antennas Using Second-Order Filter Theory
(IEEE, 2022-07)
In this article, the authors propose a lumped circuit methodology for the design of broadband stacked microstrip patch antennas fed through an aperture. First, an equivalent circuit (EC) is introduced for the antenna. The ...
