Abstract The Om-C filters are one from the two main techniques (Om-C and witched-Capacitor) used for realizing integrated analog filters. The Orn- C technique has the advantages of processing higher frequency signals range. In this thesis an electronic tunable IF bandpass Orn-C filter for FM receiver has been designed. The center frequency is chosen equal to 10.7MHz and the bandwidth equal to 200KHz. The design started by evaluating several passive architectures to choose the most suitable architecture for on chip implementation. The filter is synthesized to yield active filter with all its transconductors have the same circuit architecture, aspect ratio of the transistors, biasing conditions and control voltage in order to prevent problems due to transconductance mismatch and facilitate the filter tuning. The implemented filter is of the 2nd order that has 10 dB stopband attenuation and is covering many interesting telecommunication applications. The designed filter functionality and specifications have been verified with pre-layout simulation and post-layout simulation. A second design for the filter has been proposed in order to achieve higher stopband attenuation. |
