Abstract

This paper proposes an Operational Floating Current Conveyor (OFCC) based shadow filter configuration. The operation of the filter is based on modifying filter performance parameters with the help of gain of active block. This flexibility makes it attractive in comparison to a design, where similar control is achieved by changing values of relatively larger number of components. The proposed filter uses four active blocks (OFCCs), two grounded capacitors, and four grounded resistors and helps achieve low pass controlled low pass, high pass and band pass response. The use of grounded passive components makes proposed configuration, attractive from integrated circuit realization viewpoint. The functionality of the proposed circuit is demonstrated through SPICE simulations using the 0.5 m CMOS process model of MOSIS (AGILENT). The proposed circuit can be readily used in today's multi-standard transceivers in the IF stage for the implementation of frequency agile filters, which offer higher configurability to the transceiver chain and the analog front-end towards various standards of the ever changing industry demands.
