Computer-aided design of high-speed lattice wave digital filter integrated circuits

A silicon compiler for generating IIR filter integrated circuits based on the lattice wave digital filter structure is presented. A novel architecture has been developed to minimize the chip area while achieving a high throughput. A fifth-order filter synthesized with the compiler measures 4.17 mm/sup 2/ and has an estimated sample rate of at least 60 MHz in 0.8 mu m BiCMOS gate-array technology. This represents an order of magnitude improvement over the lattice wave digital filter compiler.<
