Dans cet article, nous discutons d'un système de rejet d'image IF avec une bande passante et une fréquence centrale variables. Le système se compose d'une paire de mélangeurs de fréquence multipliés par la sinusoïde complexe et d'un filtre analogique complexe. En utilisant la structure saute-mouton complexe utilisant la configuration OTA-C et la transformation de fréquence à partir du LPF normalisé, le système proposé est capable de caractéristiques de bande passante et de fréquence centrale variables. Les simulations SPICE aboutissent à un rejet d'image de plus de 43 [dB] pour des bandes passantes de 6 [kHz] et 12 [kHz] à 50 [kHz] IF.

Abstract: In this paper, we discuss an IF image rejection system with variable bandwidth and center frequency. The system is consists of a pair of frequency mixers multiplied by the complex sinusoid and a complex analog filter. By employing the complex leapfrog structure using OTA-C configuration and the frequency transformation from the normalized LPF, the proposed system is capable of variable bandwidth and center frequency characteristics. SPICE simulations result more than 43 [dB] image rejection is achieved for 6 [kHz] and 12 [kHz] bandwidths at 50 [kHz] IF.
