Oscillators and operational amplifiers [PDF]
Proceedings of the 2005 European Conference on Circuit Theory and Design, 2005., 2006 A generalized approach to the design of oscillators using operational amplifiers as active elements is presented. A piecewise-linear model of the amplifier is used so that it make sense to investigate the eigenvalues of the Jacobian of the differential equations. The characteristic equation of the general circuit is derived.

Memristive Operational Amplifiers
Procedia Computer Science, 2014 AbstractThe neuronal algorithms process the information coming from the natural environment in analog domain at sensory processing level and convert the signals to digital domain before performing cognitive processing. The weighting of the signals is an inherent way the neurons tell the brain on the importance of the inputs and digitisation using ...
