Wireless: From Marconi's Black-Box to the Audion
By 1897 Guglielmo Marconi had transformed James Clerk Maxwell's theory of electromagnetic waves into a workable wireless telegraphy system, and by 1907 Lee de Forest had invented the audion, aExpand
Polyphase Filter with Parametric Tuning
The development of a polyphase filter in a 0.35-μm CMOS process is proposed using Cadence Virtuoso IC tools and SPECTRE/SPECTRE-RF simulator and based on the “Filter & Hold” (F&H) concept, which represents a newpolyphase filter circuit approach with improved mixed-signal tuning capabilities when compared to several state-of-the-art implementations.

Design and Implementation Of Low Power CMOS Radio Receiver
A single-chip CMOS Global Positioning System (GPS) radio has been integrated using only a couple of external passive components for the input matching network and one external reference for theExpand
Continuous-Time Extremum Seeking with Function Measurements Disturbed by Stochastic Noise: A Synchronous Detection Approach
A novel algorithm for extremum seeking based on a stochastic continuous-time optimization approach employing a gradient descent method based on the synchronous detection technique and proves the mean-squared convergence of the suggested extremumseeking algorithm to a zone around the minimizer.

Since the first observation of current oscillations during electrodissolution of an iron wire in nitric acid by Fechner [2] in 1828, the experimental evidence of electrochemical instabilitiesExpand
Continuous-time gradient-like descent algorithm for constrained convex unknown functions: Penalty method application
A novel continuous-time gradient descent algorithm of a constrained convex unknown function with a stochastic noise in the observed data and a modified version of the synchronous detection method is suggested. Expand
Robust integral sliding mode controller for optimisation of measurable cost functions with constraints
The main contribution of the paper is the formulation of the problem using the penalty method and the development of an extremum seeking algorithm based on a modified synchronous detection method for computing a stochastic gradient descent procedure. Expand
Robust Extremum Seeking for a Second Order Uncertain Plant Using a Sliding Mode Controller
A novel continuous-time robust extremum seeking algorithm for an unknown convex function constrained by a dynamical plant with uncertainties to develop a robust closed-loop controller based on sliding modes where the sliding surface takes the trajectory around a zone of the optimal point. Expand
