Abstract :
This paper presents two second-order lowpass filters realized with operational amplifiers (OA) and operational transconductance amplifiers (OTA) only. The circuits do not require additional passive components, which makes them suitable for integrated circuit (IC) implementation and reduces chip area. The filter parameters can be adjusted independently. Simulation results are included to verify theory
