Bandwidth extension techniques for high-efficiency power amplifiers
García Tormo, Albert (Universitat Politècnica de Catalunya, 2011-04-15)
Tesi
Accés obertAquesta tesi tracta sobre amplificació de potència d'alt rendiment de senyals variables en el temps; concretament, tracta sobre conversió de potència eficient (amb mínimes pèrdues) de tensions DC continues en senyals de ... -

Alarcón Cot, Eduardo José; Fernández, Diego; García Tormo, Albert; Madrenas Boadas, Jordi; Poveda López, Alberto (IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialA mixed-signal continuous-time-processing standard CMOS implementation of an asynchronous sigma-delta modulator aimed to drive a switching amplifier operating as an on-chip wideband adaptive power supply is presented in ... -
Fundamental modulation limits for minimum switching frequency inband-error-free high-efficiency power amplifiers
García Tormo, Albert; Poveda López, Alberto; Alarcón Cot, Eduardo José; Guinjoan Gispert, Francisco (2011)
Article
Accés restringit per política de l'editorialThis paper explores the modulation bandwidth limits for switching amplifiers, by analyzing the fundamental tracking capabilities of two-level switching signals. With this aim, this work synthesizes two-level switching ... -
Multi-level asynchronous Sigma Delta modulators for wideband switching power amplifiers
García Tormo, Albert; Poveda López, Alberto; Alarcón Cot, Eduardo José; Guinjoan Gispert, Francisco (IEEE, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialThis work extends the Asynchronous ΣΔ Modulator and its Adaptive version to multi-level modulators, targeting wideband high-efficiency switching power amplifiers. The performance of these modulators is compared with the ...
