In this research, the design and implementation of an integrated circuit, digitally programmable, analog to analog filter are presented. By functioning in the analog domain the quantization errors and hardware requirements of analog to digital, and digital to analog, conversion are eliminated. The filter design of this project utilizes switched capacitors and the Generalized Immitance Converter to eliminate resistors and inductors. The resulting design is therefore suitable for fabrication by modern integrated circuit technology. The design also features digital programmability, so that the filter can easily interface with modem digital systems. The overall filtering circuit is programmable in filter topology, quality factor, and cutoff or center frequency, making it useful in a wide range of applications.
