Compact low-power calibration mini-DACs for neural arrays with programmable weights
(Institute of Electrical and Electronics Engineers, 2003)
This paper considers the viability of compact low-resolution low-power mini digital-to-analog converters (mini-DACs) for use in large arrays of neural type cells, where programmable weights are required. Transistors are ...

Log-domain implementation of complex dynamics reaction-diffusion neural networks
(Institute of Electrical and Electronics Engineers, 2003)
In this paper, we have identified a second-order reaction-diffusion differential equation able to reproduce through parameter setting different complex spatio-temporal behaviors. We have designed a log-domain hardware that ...

On the design and characterization of femtoampere current-mode circuits
(Institute of Electrical and Electronics Engineers, 2003)
In this paper, we show and validate a reliable circuit design technique based on source voltage shifting for current-mode signal processing down to femtoamperes. The technique involves specific-current extractors and ...

A calibration technique for very low current and compact tunable neuromorphic cells: Application to 5-bit 20nA DACs
(Institute of Electrical and Electronics Engineers, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as a few nanoamperes or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precisions. Recently, ...
