Abstract
This work puts forward a universal transadmittance mode (TAM) filter topology based on a differentiator approach using an analog building block known as operational floating current conveyor (OFCC). The proposed topology uses three OFCC blocks, two grounded capacitances, and three grounded resistances. This circuit has a number of advantages which make it highly suitable for a number of applications. All the passive elements of the circuit are grounded which make it highly favorable from fabrication point of view. The circuit has high input as well as high output impedance. The proper impedances of the circuit make it suitable for interfacing between voltage mode and current mode circuits. The pole frequency of the circuit is electronically tunable using MOS transistor-based implementation of grounded resistances. SPICE simulations using 0.5 µm technology parameters from MOSIS (AGILENT) are provided.
