The noise power wave formalism is used to extract the noise parameters from the noise power measurement. A first step consists of calibrating the measurement setup. We only assume that the receiver is unidirectional. The noise parameters are then deduced from power measurements with analytical relations with no further assumptions.
Silicon technologies are now widely used for RF applications. Due to the substrate and conductor conductivity, losses and magnetic coupling affect the signal propagation in transmission lines. We propose an equivalent scheme for a transmission line taking these phenomena into account. All the parameters are analytically extracted from measurements. The… (More)
A dual wide band low noise amplifier for WiMAX (802.16a) standard is presented. The circuit is designed with AMS 0.35 mum CMOS process. This LNA is designed to cover the two frequency ranges for licensed and unlicensed bands of the WiMAX 2-4 GHz and 5-6 GHz. The proposed amplifier achieves a wide band input matching with Sn lower than -10 dB for all the… (More)
This paper introduces flexible radio techniques inside integrated circuits in order to tackle the interconnect issue for many-core chips. We propose to take benefits from OFDMA for a RF-interconnect associated to a carrier allocation policy and adaptive modulation. A 20 GHz bandwidth is shared between 32 tile sets made of 32 tiles of 4 cores each, for a… (More)
