Abstract :
A fully integrated recursive charge transfer multibridge filter (MBF) is described using the concept of passive recirculation of charges. This is a novel solution for voice channel filters in digital communications. The MBF is constituted of a recursive routing structure and of a split electrode array. The structure behavior is investigated in terms of its state variables. Preliminary experimental results are reported on 13-bridge and 9-bridge filters.
