A 3.3 V 350 MHz 0.35 µm CMOS programmable RIF based on redundant coding in a bit plane architecture

A 350 MHz programmable RIF was realised. This filter is used as a basic circuit in a terrestrial 622 Mbit/s ATM distribution system. In addition to the filtering function, multiplication, addition, saturation and inversions at the same 350 MHz clock rate frequency are processed. The technological process is five-metal 3.3 V 0.35 μm CMOS.
