Abstract :
A transversal filter, based on a novel cell design that enables positive and negative tap gain weight control, is presented. The design process is described and it involves the selection of variables to set the filter bandwidth and propagation characteristics of its artificial transmission lines. Such method allows filter implementations where pulse shape integrity needs to be preserved. Time domain analysis shows that the filter can handle picosecond pulses satisfying the first Nyquist criterion. Results describe a monolithic microwave integrated circuit (MMIC) design for 40 Gbit/s systems applications and suitable for both sequence generation and detection in 40 GChip/s CDMA systems.
