Abstract :
We present a MEMS, switched current mode circuit that realizes a multi-ear type system. A novel sensor, acts as a pressure transduction mechanism for input to cochlear-type processing. Z-transform computation of fluid motion in the tubules of the cochlea is realized with a switched current lattice cascade. We also describe how an array of MEMS-SI circuits can be placed for use as a multisensor, intended for sound-beam forming, accomplished with n-aural hearing
