Circuit design proposal for multi-GBit/s CDMA over fibre using distributed topologies

A novel circuit design technique for integrated circuits capable of encoding and decoding high-speed spread spectrum signals is proposed and verified by simulation. The transversal distributed topology allows operation at speeds close to the cut-off frequency of the transistors employed. Results describe a Monolithic Microwave Integrated Circuit (MMIC) compatible with 40 GBit/s systems applications and suitable for signal generation and detection in 40 GChip/s CDMA systems.
