ABSTRACT:
The invention is directed to a bi-quad filter circuit configured with sigma-delta devices that operate as binary rate multipliers (BRMs). Unlike conventional bi-quad filter circuits, the invention provides a bi-quad filter configured with a single-bit BRM. In another embodiment, the invention further provides a bi-quad filter configured with multiple-bit BRMs.
