The circuit performs continuous-time gradient descent using simultaneous perturbation gradient estimation. Simulations were performed using Agilent ADS circuit simulator. Field tests were performed in a realistic scenario using a satellite signal. The results were comparable to the simulation predictions and to results obtained using a digital implementation of a similar stochastic approximation algorithm.enantenna beamforminganalog processorsmart antennasanalog processingstochastic approximationgradient descentku bandantennaMaster ThesisElectrical and Computer Engineering
