Design considerations for biomedical signal interfaces

In this paper, IC design considerations for preamplifiers and filters intended for analog preprocessing of biomedical signals are discussed. A revision of previously reported design techniques is carried out, and several design challenges are mentioned. Special attention is paid to implantable devices, and systems where small die area, very low power consumption and a minimal number of external components are a must.
