| Abstract: | In This paper, a practical receiver circuit for USB HUB Low/Full-Speed Mode transceivers is discussed. It uses tow-stage differential amplifiuers to increasee the circuit gain and uses a source follower as a voltage buffer to decrease signal volt- age losing. The receiver circuit been implemented by CSMC 0. 6um Nwell Standard CMOS process and provd to conform to the USB 1. 1 Specification. This circuit has been used in the design of a USB HUB chipset. |
