—An 802.11a compliant medium access control (MAC) and physical layer (PHY) processing chip has been successfully fabricated in 0.18-m CMOS. Thirty million transistors are integrated on a 10 91 10 91 mm 2 die housed in a 361-pin PFBGA. The MAC functions are fully implemented by firmware on an embedded 32-b RISC processor, 4-Mb SRAM, and hardware acceleration(More)
