Abstract:
La détection IR quantique met classiquement en jeu l'absorption de photons dans le matériau semi-conducteur II-VI CdHgTe. Cet alliage présente la particularité de permettre un ajustage du gap du semi-conducteur aux longueurs d'onde couvrant toute la gamme IR en jouant simplement sur la composition de l'alliage, ce qui en fait un matériau de choix. Cependant,les petits gaps en jeu ici imposent un refroidissement des plans focaux à des températures généralement cryogéniques (typiquement la centaine de Kelvins). Ce refroidissement représente naturellement une limite importante dans l'exploitation

Abstract:
Kadmium telurid je velmi důležitý materiál jak základního, tak i aplikovaného výzkumu. Je to dáno zejména jeho výhodnými elektronickými, optickými a strukturními vlastnostmi, které ho předurčují pro náročné technické aplikace. Dnes se hlavně používá pro jeho vysoké rozlišení k detekci a X-záření. Hlavní výhodou detektorů na bázi CdTe je, že nepotřebují chlazení a mohou spolehlivě fungovat i při pokojové teplotě. To způsobuje efektivnější interakce fotonů než je tomu u Si nebo jiných polovodičových materiálů. Obsahem této práce byla analýza a interpretace výsledků získaných studiem šumových a

Abstract:
Minimizing electrical noise is an increasingly important topic. New systems and modulation techniques require a lower noise threshold. Therefore, the design of RF and microwave systems using low noise devices is a consideration that the circuit design engineer must take into account. Properly measuring noise for a given device is also vital for proper characterization and modeling of device noise. In the case of an oscillator, a vital part of a wireless receiver, the phase noise that it produces affects the overall noise of the system. Factors such as biasing, selectivity of the input and outp

As the technology is advances the reduced size of hardware gives rise to an additive 1/f baseband noise. This additive 1/f noise is a system noise generated due to miniaturization of hardware and affects the lower frequencies. Though 1/f noise does not show much effect in wide band channels because of its nature to affect only certain frequencies, 1/f noise becomes a prominent in OFDM communication systems where narrow band channels are used. in this thesis, I study the effects of 1/f noise on the OFDM systems and implement algorithms for estimation and suppression of the noise using Kalman fi

Radiation-induced trapped charge density was found to have a large effect on the magnitude and slope of the noise. Irradiation of devices was found to produce a more uniform distribution in time constants leading to the more ideal 1/f noise power

Low-frequency noise (LFN) is characterized using in-house measurement systems in a variety of SiGe HBT generations. As technology scales to improve the performance and integration level, a large low-frequency noise variation in small geometry SiGe HBTs is first observed in 90 GHz peak fT devices. The fundamental mechanism of this geometry dependent noise variation is thought to be the superposition of individual Lorentzian spectra due to the presence of G/R centers in the device. The observed noise variation is the result of a trap quantization effect, and is thus best described by number fluc

Abstract:
La détection infrarouge, autrefois réservée aux applications militaires et spatiales, connait depuis une dizaine d’années une mutation importante et s’ouvre de plus en plus vers des marchés "grand public". Cette démocratisation est principalement liée aux développements rapides que connaissent les technologies utilisant des bolomètres "non refroidis", qui profitent de leurs compatibilités avec les filières de la microélectronique.La technologie utilisée au CEA/LETI repose sur l’utilisation d’un matériau thermomètre à base de silicium amorphe (également noté "a-Si"). Ce dernier comporte de nomb

Abstract:
La technologie des microbolomètres est à ce jour la plus avancée pour l'imagerie IR non refroidie. Le LETI développe une technologie basée sur l'utilisation du silicium amorphe comme matériau thermistor. L'introduction d'un matériau alternatif doit permettre de poursuivre l'amélioration des performances. Cette étude considère une solution alternative à base de films minces d'oxydes nanocristallins. Deux procédés sont envisagés : le dépôt IBS et le dépôt MOCVD. L'étude des procédés ainsi que la caractérisation des matériaux ont permis la maîtrise et la compréhension des évolutions structurales

Abstract:
Les résonateurs à ondes acoustiques de volume (BAW) ont été étudiés dans le domaine temps-fréquence à FEMTO-ST depuis longtemps et ont montré un rôle essentiel dans de nombreuses applications métrologiques telles que dans les dispositifs de positionnement comme GPS, Glonass, Galileo, etc. Ce travail de thèse présente la technique passive utilisée pour des mesures du bruit de phase dans les résonateurs BAW à quartz. Les résonateurs BAW de hautes performances ont été fabriqués par plusieurs fabricants européens et fournis par le CNES pour une étude de “reverse engineering” durant cette thèse. Le
