Abstract
An operational floating current conveyors (OFCC)-based single-input multiple-output transadmittance mode filter is presented in this paper. The circuit uses only three OFCC, two grounded capacitors and three grounded resistors. The independent electronic adjustment of filter parameters is achieved through MOSFETs-based implementation of grounded resistors. The sensitivity of filter parameters is found to be within unity. The nonideal study is also incorporated that takes parasites and finite transimpedance of OFCC into account. SPICE simulations using 0.5μm CMOS process model provided by MOSIS (AGILENT) have been included to verify the functionality of the proposed circuit. The impact of process variation on the proposed filter is also studied.
