    Araguz López, Carles; Llaveria Godoy, David; Lancheros Sepulveda, Estefany Maria; Bou Balust, Elisenda; Camps Carmona, Adriano José; Alarcón Cot, Eduardo José; Tonetti, Stefania; Cornara, Stefania; Vicario, Gonzalo; Lluch i Cruz, Ignasi; Matevosyan, Hripsime; Golkar, Alessandro; Cote, Judith; Pierotti, Stéphane; Rodríguez, Pedro; Alvaro Sanchez, A.; Sochacki, Mateusz; Narkiewicz, Janusz (2019-01-25)
    Article
    Open Access
    Earth observation satellite programs are currently facing, for some applications, the need to deliver hourly revisit times, subkilometric spatial resolutions, and near-real-time data access times. These stringent requirements, ...
  • CMOS RF first-order all-pass filter 

    Aghazadeh, Seyed Rasoul; Martínez García, Herminio; Saberkari, Alireza; Alarcón Cot, Eduardo José (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
    Conference report
    Open Access
    In this paper, a wide-band first-order voltage-mode all-pass filter is presented. Due to a simple structure and appropriate performance of the proposed all-pass filter, this filter achieves a flat group delay of over 60 ...
