A 19 nW analogue CMOS log-domain 6th-order Bessel filter without E-minus cells

HMD Ip, EM Drakakis, AA Bharath�- Microelectronics Journal, 2009 - Elsevier
This paper contributes to the field of low-power high-order CMOS log-domain filters by: (a)
suggesting a log-domain synthesis path which bypasses the need for E-minus cells and (b) by …

[PDF][PDF] Analogue CMOS cochlea systems: a historic retrospective

A Katsiamis, E Drakakis�- BASED APPLICATIONS, 1982 - core.ac.uk
… A build-in microphone front-end (using the commercial JFET-buffered FG3329) electret
microphone to transduce sound into an electrical signal. The microphone front-end was …

Preliminary results from an analog implementation of first‐order TDCNN dynamics

HMD Ip, EM Drakakis…�- International Journal of�…, 2011 - Wiley Online Library
This work falls into the category of linear cellular neural network (CNN) implementations. We
detail the first investigative attempt on the CMOS analog VLSI implementation of a recently …

A nonseparable 3D spatiotemporal bandpass filter with analog networks

HMD Ip, EM Drakakis…�- 2008 IEEE International�…, 2008 - ieeexplore.ieee.org
using a modified version of the linear Cellular Neural Network (CNN) filtering paradigm

An automatic transimpedance gain control circuit for analogue front-ends of drifting amperometric biosensors

I Pagkalos, EM Drakakis�- Measurement, 2017 - Elsevier
When amperometric biosensors drift, their sensitivity drops with time: the same difference in
detected concentration value Δ C results in lower sensor output current Δ I as the …

Modified spectral subtraction for de-noising heart sounds: Interference suppression via spectral comparison

…, RJ Dickinson, EM Drakakis�- 2008 IEEE Biomedical�…, 2008 - ieeexplore.ieee.org
… For each heart sound, a recording was taken at two distances – first with the front
microphone in contact with the transmission surface and second with the front microphone one …

Silicon experimentation of first order TDCNN dynjamics

HMD Ip, EM Drakakis…�- 2010 12th International�…, 2010 - ieeexplore.ieee.org
Recently, the authors have proposed a network formalism (TDCNNs) which introduces Time-Derivative
coupling between linearized-CNN cells (with output nonlinearity removed) and …

constraints in the data bandwidth of the RF link transmitting the processed microphone input to the …

On analog networks and mixed-domain spatio-temporal frequency response

HMD Ip, EM Drakakis…�- IEEE Transactions on�…, 2008 - ieeexplore.ieee.org
In this paper, we extend the linear cellular neural network (CNN) paradigm by introducing
temporal derivative diffusion connections between neighboring cells. Our proposal results in …
