Research Abstract |
The performance of recent high-speed VLSI systems is significantly limited by the interconnection bandwidth inside/between chips relative to individual transistor performance. The attenuation or deterioration of signals, arises from physical phenomena in transmission lines, limits achievable data rates and transmission distance. In this research, we have proposed following techniques to overcome the issues. (1)A new type of transmitter pre-emphasis technique based on pulse-width modulation (PWM) of a digitally coded signal. (2) An Efficient data coding scheme suited to channel characteristics and its application to wireless interconnection for 3D ICs.
