This title deals with the design and analysis of log-domain filter circuits. It describes synthesis methods for developing bipolar or BiCMOS filter circuits with cut-off frequencies ranging from the low kilohertz range to several hundred megahertz. Numerous examples provide measured experimental data from IC prototypes.
