Abstract

A low-power switching method using a bootstrapping circuit is proposed for a high-speed output driver of transmitter. Compared with a conventional output driver, the proposed scheme employs only nMOSFETs to transmit data. The bootstrapping circuit ensures the proper switching of nMOSFET. The proposed scheme is simulated and fabricated using a 0.18µm CMOS technology, showing 10.2% lower power consumption than a conventional switching driver at 2.5Gb/s data rate.
