We present a mixed-signal very-large-scale-integrated chip that emulates nonlinear active cochlear signal processing. Modeling the cochlea's micromechanics, including outer hair cell (OHC) electromotility, this silicon (Si) cochlea features active coupling between neighboring basilar membrane (BM) segments-a first. Neighboring BM segments, each implemented as a class AB log-domain second-order section, exchange currents representing OHC forces. This novel active-coupling architecture overcomes… 
Design of a silicon cochlea system with biologically faithful response
TLDR
The proposed silicon cochlea is feasible for analog VLSI implementation so that it not only emulates the way that sounds are preprocessed in human ears but also is able match the compact physical size of a real coChlea.
A Bio-Realistic Analog CMOS Cochlea Filter With High Tunability and Ultra-Steep Roll-Off
TLDR
A parallel bank of the proposed filter can be used as the front-end in hearing prosthesis devices, speech processors as well as other bio-inspired auditory systems owing to its bio-realistic behavior, low power consumption and small size.
Biomimetic cochlea filters : from modelling, design to analogue VLSI implementation
This thesis presents a novel biomimetic cochlea filter which closely resembles the biological cochlea behaviour. The filter is highly feasible for analogue very-large-scale integration (VLSI)
Psychophysical Evaluation of An Ultra-Low Power, Analog Biomimetic Cochlear Implant Processor Filterbank Architecture With Across Channels AGC
TLDR
An ultra-low-power, analog biomimetic cochlear-implant (CI) processor filterbank architecture that emulates the lateral inhibition mechanism by employing an automatic gain control scheme that is coupled across One-Zero-Gammatone-Filter (OZGF) channels is evaluated.
A hardware model of the auditory periphery to transduce acoustic signals into neural activity
TLDR
An artificial peripheral auditory system is constructed using a hybrid model in which polyvinylidene difluoride was used as a piezoelectric sensor to convert mechanical stimuli into electric signals to improve the performance of cochlear implants.
An Analog VLSI Implementation of the Inner Hair Cell and Auditory Nerve Using a Dual AGC Model
TLDR
An analog inner hair cell and auditory nerve circuit using a dual AGC model has been implemented using 0.35 micron mixed-signal technology and the ability to correct channel mismatch is evaluated with matched layouts as well as with digital current tuning.
Asynchronous Binaural Spatial Audition Sensor With 2$\,\times\,$64$\,\times\,$4 Channel Output
TLDR
It is shown that the computational cost of an event-driven source localization application can be up to 40 times lower when compared to a conventional cross-correlation approach.
${\rm A}~6~{\mu{\rm W}}$ per Channel Analog Biomimetic Cochlear Implant Processor Filterbank Architecture With Across Channels AGC
TLDR
A new analog cochlear implant processor filterbank architecture of increased biofidelity, enhanced across-channel contrast and very low power consumption has been designed and prototyped and is well-suited for fully-implantable co chlear implants.
Making Use of Auditory Models for Better Mimicking of Normal Hearing Processes With Cochlear Implants: The SAM Coding Strategy
TLDR
Results show that aspects of normal cochlear processing that are missing in common strategies can be replicated by SAM, which is supposed to improve overall CI user performance and is at least partly proven in a pilot study with implantees.
