摘要

提出了一种用于高速无线通信的多频段正交频分复用(MB-OFDM)超宽带(UWB)调制解调器设计。所开发的芯片的媒体访问控制(MAC)/物理层(PHY)部分基于WiMedia标准。采用ARM9进行高速数据处理,主机接口支持usb2.0和SDIO。调制解调器部分约占整个芯片面积的一半,使用了大部分标准单元来开发。采用90nm CMOS技术,芯片尺寸约5mm × 5mm。采用电源管理模式,降低平均功耗。

Design and implementation of MB-OFDM UWB modem
A multi-band orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) modem design for high speed wireless communication is presented. The media access control (MAC)/ physical layer (PHY) part of the developed chip is based on the WiMedia standard. ARM9 is adopted for high speed data transaction and USB 2.0 and SDIO are supported for host interface. The modem part occupies about half of the whole chip area, and is developed by using most of standard cells. 90nm CMOS technology is used and the chip size is about 5mm × 5mm. The power management mode is implemented to reduce the average power consumption.
