Abstract:Support vector machines (SVMs) are a very popular machine-learning algorithm used in many systems today. In some applications, having the classifier built into a chip can allow for low-power and efficient operation. With this in mind, in this senior thesis multiple radial basis function (RBF) circuits for classification are implemented in a 180-nm-process technology. After evaluating the power, energy, delay, and accuracy of different circuit architectures, the Gilbert Gaussian and a newly proposed complementary bump circuit were shown to be the best for implementing in a support vector machine classifier. The two-dimensional Gilbert Gaussian circuit has the most accurate performances, whereas the newly proposed two-dimensional complementary bump circuit has the smallest area. Moreover, the proposed bump circuit also has smaller energy and power consumption than the Gilbert Gaussian circuit at the same input current levels.
