Abstract
Enhanced with LSI technology scaling, the frequency-dependent attenuation of the transmission lines between chips, PCBs, etc, becomes the obstacle to improve the system performance. Because, large frequency-dependent attenuation gives poor eye-opening and high bit-error rate in data transmission. This paper presents a 5-Gb/s 10-meter 28AWG cable transceiver by using 0.13-μm CMOS technologies. In this transceiver, a continuous-time post-equalizer with recently developed no-feedback-loop high-speed analog amplifiers can handle up to 9 dB of frequency-dependent attenuation in cables, and an 18-dB improvement in the attenuation (27 dB in total) can also be achieved by using the pre- and post-equalization techniques in combination.
