In this paper low power circuit design is investigated. Energy-delay product is selected as an useful metrics and effects of transistor sizing are explained and a graphical method to determine supply and threshold voltage of the circuit is proposed. It has been shown that how transistor width could change these optimal voltages.
—This paper deals with the possibilities of cancellation of unwanted signals by steering nulls of the pattern in the direction of arrival of signal while keeping the main beam to the desired direction. New iterative adaptive digital beam forming technique is presented here to enhance the conventional effectiveness of beam forming in common commercial… (More)
