Current-mode fully-programmable piece-wise-linear block for neuro-fuzzy applications
(Institute of Electrical and Electronics Engineers, 2002)
A new method to implement an arbitrary piece-wise-linear characteristic in current mode is presented. Each of the breaking points and each slope is separately controllable. As an example a block that implements an N-shaped ...

On the Design of Voltage-Controlled Sinusoidal Oscillators Using OTA's
(Institute of Electrical and Electronics Engineers, 1990)
A unified systematic approach to the design of voltage-controlled oscillators using only operational transconductance amplifiers (OTA's) and capacitors is discussed in this paper. Two classical oscillator models, i.e., ...

Integration of nanoscale memristor synapses in neuromorphic computing architectures
(Institute of Physics Publishing, 2013)
Conventional neuro-computing architectures and artificial neural networks have often been developed with no or loose connections to neuroscience. As a consequence, they have largely ignored key features of biological neural ...

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems
(Institute of Electrical and Electronics Engineers, 2007)
We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between ...

Fast Predictive Handshaking in Synchronous FPGAs for Fully Asynchronous Multisymbol Chip Links: Application to SpiNNaker 2-of-7 Links
(Institute of Electrical and Electronics Engineers, 2016)
Asynchronous handshaken interchip links are very popular among neuromorphic full-custom chips due to their delay-insensitive and high-speed properties. Of special interest are those links that minimize bit-line transitions ...
