Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

Exploiting memristance for implementing spike-time-dependent-plasticity in neuromorphic nanotechnology systems
(2009)
In this paper we show that STDP can be implemented using a crossbar memristive array combined with neurons that asynchronously generate spikes of a given shape. An attenuated version of such spikes needs to be sent ...
