A 1V 357Mb/s-throughput transferjet™ SoC with embedded transceiver and digital baseband in 90nm CMOS

TransferJet™, based on DSSS-UWB, is a promising standard protocol which provides users high-speed, short-range, simple-usage, low-power and robust connectivity. Since its communication distance is limited to a few centimeters, the required TX output power is small enough to meet regulatory restrictions in many countries. This paper presents the first SoC that implements PHY and Connection Layer (CNL) functionality from the TransferJet™ and ECMA-398 standards. All the RF building blocks as well as digital baseband are integrated including PHY, CNL and SDIO 3.0 device controller. A coupler and an RF BPF are the only external components required to complete a wireless system.

A DSSS UWB digital PHY/MAC transceiver for wireless ad hoc mesh networks with distributed control

A DSSS UWB digital PHY/MAC transceiver with distributed control has been developed. This chip provides fast acquisition within 8mus and plusmn7.5cm ranging accuracy, as well as distributed wireless access control of up to 64 terminals and a power save control function. Die area is 12.2mm2 in a 0.13mum CMOS process. The maximum power dissipation of the core is 181mW at 1.2V
