Abstract
The research on the design of receiver front-ends for very high data-rate communication in the 60 GHz band in nanoscale CMOS technologies is going on for some time now. While a multitude of 60 GHz front-ends have been published in recent years, they are not consequently optimized for low power consumption. Thus, these front-ends dissipate too much power for battery-powered applications like handheld devices, mobile phones and wireless sensor networks. This article describes the design of a direct conversion receiver front-end that addresses the issue of power consumption, while at the same time permitting low cost (due to area minimization by the use of spiral inductors). It is implemented in a 65 nm CMOS technology. The realized front-end achieves a record power consumption of only 43mW including lownoise amplifier (LNA), mixer, a voltage controlled oscillator (VCO), a local oscillator (LO) buffer and a baseband buffer (without this latter buffer the power consumption is even lower,only 29mW). Its pad-limited size is 0.55×1 mm². At the same time, the front-end achieves state-of-the-art performance with respect to its other properties: Its maximum measured power conversion gain is 30dB, the RF and IF bandwidths are 56.5-61.5 GHz and 0-1.5 GHz, respectively, its simulated minimum noise figure is 8.4 dB and its measured IP-1dB is -36 dBm.

Abstract
The paper is focused on the design of a new reconfigurable tactical UWB impulse radio enabling indoor communication and localization for military application. The proposed system contains both a physical and a MAC (Medium Access Control) layer. It proposes to answer military needs for information sharing and for indoor localization of infantry. The physical layer is based on IR-UWB (Impulse Radio Ultra WideBand). Its goal is to ensure communication and distance evaluation between the transmitter and the receiver. IR-UWB is necessary for constraints such as low power consumption, reconfigurability, through the wall propagation, fine resolution localization, low probability of detection and interception. These advantages come from the use of a very large bandwidth with very short pulses. The digital baseband implementation of a reconfigurable IR-UWB transceiver is based on a coherent Rake receiver and on a parallel search acquisition. Its synchronization accuracy is of 0.33 ns. This enables distance evaluation with a precision of 10 cm. The MAC layer deals with the multi user access and the positioning. TDMA is used for sharing the channel between users. WiDeCS, a master-slave TOA (Time of Arrival) cross layer mechanism is implemented for time synchronization. This algorithm can also determine the Time of Flight of the IR-UWB signal due to timestamps at the physical layer. This algorithm followed by triangulation and-or angle of arrival techniques leads to 3D positioning.
