The aim of this paper is threefold. First, it reviews the low-noise amplifier and its relevance in wireless communications receivers. Then it presents an exhaustive review of the existing topologies. Finally, it introduces a new class of LNAs, based on current conveyors, describing the founding principle and the performances of a new single-ended LNA. The(More)
Several communication techniques are investigated in the first part of this paper: software radio, cognitive radio and encrypted communications. State of the art of research on agile and reconfigurable filters, passive as well as active, necessary for transceivers is then made and various tables for comparison are given. In the third part, a new theory for(More)
The aim of this paper is 3-fold: firstly, to provide a comprehensive overview of the use of differential circuits for analogue signal processing in wireless transceivers; secondly, to describe, in detail, single-ended signal to differential conversion, and the corresponding theory of such devices, their charac-terisation, various methods of implementation,(More)
Indexing the gender of the speaker or the addressee within any type of sentence is often considered as sociolinguistic variation rather than as a gender-exclusive rule. This paper presents a survey of categorical (rather than statistical) gender indexicality in grammar with the greatest number of languages to date. It also offers a data-informed typology of(More)
The aim of this paper is threefold. First, it introduces the low-noise amplifier, its relevance in modern wireless communications receivers and the performance expected of it. Then, it presents an exhaustive review of the existing topologies, presenting their advantages and shortcomings. And finally, it introduces a new class of LNAs, based on current(More)
