On the design of low-frequency filters using CMOS OTAs operating in the subthreshold
On the design of low-frequency filters using CMOS OTAs operating in the subthreshold
Design considerations on a circuit technique based on subthreshold operation of MOS transistors is described for the realization of low-frequency OTA-C active filters with small capacitance values of the order of 25-400 pF. The circuit technique described is applied to the $alpha@(8-12 Hz), $beta@(13-40 Hz), $theta@(4-8 Hz) and $delta@(1-4 Hz) band filters for EEG signals. Because of small capacitance values the filter circuit is suitable for realization on a single VLSI chip using the CMOS technology, and enables the user to implement the circuit on implantable biotelemetric applications.

Abstract
Design considerations on a circuit technique based on subthreshold operation of MOS transistors is described for the realization of low-frequency OTA-C active filters with small capacitance values of the order of 25-400 pF. The circuit technique described is applied to the $alpha@(8-12 Hz), $beta@(13-40 Hz), $theta@(4-8 Hz) and $delta@(1-4 Hz) band filters for EEG signals. Because of small capacitance values the filter circuit is suitable for realization on a single VLSI chip using the CMOS technology, and enables the user to implement the circuit on implantable biotelemetric applications.
