In this paper we present the analog on-chip learning architecture of a gradient descent learning algorithm: the Weight Perturbation learning algorithm. From the circuit implementation point of view, our approach is based on current mode and trans-linear operated circuits. The proposed architecture is very efficient in terms of speed, size, precision and power consumption; moreover, it exhibits also high scalability and modularity.
