The Moore’s Law has benefited us a lot since 1970s. As conceptualized by R. Dennard [1],one can obtain transistors with higher speed and lower energy consumption in reducingthe critical dimensions and keeping the electrical field constant. This concept made thecontinuous trend of increase in integration density of CMOS (Complementary MetalOxide-Sil...
The signals of the new communication standards (LTE) show a great difference between the peak and its average power (PAPR) being unsuitable for use with conventional power amplifiers because they present maximum efficiency only when working with maximum power. Doherty power amplifiers for presenting a constant efficiency for a wide power range repr...
This thesis concentrates on reliability-aware methodology development, reliability analysis based on simulation as well as failure prediction of CMOS 65nm analog and mixed signal (AMS) ICs. Sigma-Delta modulators are concerned as the object of reliability study at system level. A hierarchical statistical approach for reliability is proposed to anal...
Les signaux des nouveaux standard de communications (LTE) ont une grande différence entre la puissance maximale et moyenne (PAPR), cela n'est pas favorable pour l'utilisation dans les amplificateurs conventionnels vu qu'ils présentent un rendement maximale seulement quand ils travaillent au niveau de puissance maximale. Des amplificateurs de puissa...

Un Convertisseur Analogique-Numérique (CAN) pour les applications spatiales en astrophysique et cosmologie a été développé au cours de cette thèse. Cette catégorie de circuits demande des bandes passantes très larges, de très hautes fréquences d'échantillonnage et une faible résolution. L architecture flash a été retenue pour sa rapidité et sa band...
This paper presents a single-balanced direct down conversion mixer for the unlicensed 60 GHz band. It is based on a differential pair employing the current bleeding technique. An integrated 60 GHz wideband passive balun allows the use of a single ended local oscillator (LO). The circuit is fabricated using the 65nm bulk CMOS technology of ST Microe...
This paper presents a low-power balanced dual-gate direct up-converter for the unlicensed 60 GHz band. To the author's knowledge, the proposed architecture has never been used for a CMOS up-converter working in this band before. The maximum conversion gain achieved by the fabricated test circuit for PLO = 6dBm, fLO = 62GHz and fIF = 1GHz is -2.4 dB...
Millimeter-wave pads based on a 65nm CMOS technology from STMicroelectronics have been designed and measured. A pad was optimized to minimize losses caused by a ground shield and by the conductive substrate. Modelling techniques and special cares to design a millimeter pad with a minimum of effects are highlighted. The goal is to integrate this pad...
