Abstract
With the ever-growing CMOS process technique and the increasing of multimedia applications, the demand of bandwidth for data transmission has increased. As the demand of high bandwidth links for high speed communication is increasing, the development of chip-to-chip interconnect plays an important role. When data rate goes up to Gbps, the signal quality will be limited by the transmission line. One important characteristic of a transmission line is that it functions as a low-pass filter which will attenuate the high frequency component of a transmitted data. Among the existing solutions, pre-emphasis in transmitter and equalizer in receiver are mostly used. However, making a pre-emphasis circuit in transmitter adaptive is not an easy work due to the lack of the received signal information in the receiver. Unless a backplane trace or bidirectional technique is used, the adaptive pre-emphasis becomes feasible. In this Thesis, we propose a simultaneous bidirectional transceiver using an adaptive pre-emphasis architecture to overcome the channel high-frequency loss and hence improve the transmitted data rate.
