Abstract

An integrable 60Hz continuous time active-RC notch filter is presented. This is made possible through replacing passive resistors by R-2R ladders providing area saving of approximately 120 times. The proposed filter is to be embedded into instrumentation amplifier for biopotential measuring devices. Simulation results of a fully differential 4th-order filter show notch depth of 68dB and THD of better than -70dB while consuming 18μW.
