Switched Capacitor Band-Pass Filter
Switched Capacitor Band-Pass ObjectTheobjectofthisexperimentistodesig nandimplementafourth-orderChebyshevband- passfilter using a Switched - Capacitor realization. The specifications of thefilter are: , center frequencyfC=4kHz, 3dBbandwidthf3dB=2kHz,gainatthecenter frequencyHBP=1. The transfer function is to be realized as the product of asecond-order high-passfilter in cascade with a second-order obtain the transfer function for thefilter, see page 13 of the Filter Potpourri. Followthe example for the8thorder band-passfilter to solve for the required value ofxandBin thefrequency transformation from a low-passfilter function to a band-passfilter function.
Because switched capacitor filters are digital circuits, the appropriate mathematical arti fice to analyze them is the ztransform. However, classical frequency domain analysis is su ffi-
