Recently, system-on-chip (SoC) solutions have been realized by integrating not only complex digital processing but also extensive analog and radio frequency (RF) circuits in a single chip. This paper presents a novel RF self test methodology suitable for complex radio SoC's. The proposed methodology employs the digital processor embedded in an SoC to enable self-testing using low-cost digital automatic...
An all-digital polar transmit (TX) architecture exhibits advantages of low cost, low power, as well as reconfigurability with full usage of digital computational power [1,2,6]. The design challange is the need for continuous innovation to further enhance power efficiency and minimize silicon area while achieving the best-in-class RF performance. The design must also meet the increaing demand of concurrent...
In this paper, we present a low-power high-performance WiMAX chipset fully compliant with IEEE 802.16e specification corrigendum 1, 2 for mobile broad band access and WiMAX Forum System Profile Wave2. The chipset is comprised of a 632.7mW modem/router chip and a 364mW RF transceiver chip, both devel oped in 65nm CMOS. A fully programmable SIMD processor is used for WiMAX baseband and only parts of...
