In this paper, the design methodology of a fully integrated gm-C, 0.5-7Hz band-pass amplifier is presented. The amplifier is designed to be employed in signal conditioning of a piezoelectric accelerometer, which is part of an implantable biomedical device. Transconductances of the OTAs range from 30pS to 100nS. Such low values of transconductances, which are required owing to the large time-constants involved, were obtained with the aid of a current division technique. Measurement results for OTA structures and part of the filter fabricated in a standard 0.8μm technology are presented.
