Abstract
Cordic based IIR digital filters possess desirable properties for VLSI implementation such as local connection, regularity, and good finite word-length behavior, but can't be pipelined to finer levels (such as bit or multi-bit levels) due to the presence of feedback loops. In this paper, a pipelining method for the cordic based IIR digital filters is proposed using the constrained filter design methods and the polyphase decomposition technique. Using this method, the filter sample rate can be increased to any desired level.
