High-speed, low-power transmitter based on charge redistribution for NoC links

In this letter, a differential capacitive charge redistribution transmitter (DCC) is proposed as a novel design to replace traditional differential transmitters, for the purpose of reducing the power consumption and increasing the data transmission rate. DCC generates a pair of differential low-swing signals through charge redistribution. Its capacitively driven mode enables high-speed transmission and extends the bandwidth. Simulation shows that DCC can achieve 11Gb/s data rate over 2mm twisted differential interconnects with only 71fJ/b power consumption.
