Abstract
A micropower tone-control circuit comprising two first-order log-domai n filters and a subtractor built with MOS transistors in weak inversio n is described. The tone-controller is capable of providing bass cut/b oost and treble cut operations. This circuit is being used in new desi gns of a conventional (acoustic) hearing-aid and cochlear implant.
