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.
