This paper presents the design of a fully integrated ultra-wideband (UWB) pulse generator for the Federal Communications Commission (FCC) 3.1-10.6-GHz band. This generator is reserved for medium rate applications and achieves pulses for an on-off keying (OOK) modulation, pulse position modulation, or pulse interval modulation. This UWB transmitter is based(More)
In this paper, an overview of the NEWSKY project is given. This project is funded by the European Commission within the 6th framework program and starts in January 2007. The NEWSKY project is a feasibility study to clarify if it is possible to establish a heterogeneous network for aeronautical communications which is capable to integrate different(More)
The design of a fully integrated CMOS low noise amplifiers (LNA) for ultra-wide-band (UWB) integrated receivers is presented. An original LC input matching cell architecture enables fractional bandwidths of about 25%, with practical values, that match the new ECC 6–8.5-GHz UWB frequency band. An associated design method which allows low noise figure and(More)
Impact of substrate noise on a 6-10 GHz low noise amplifier (LNA) is investigated in this work. The measurement results show significant substrate noise in the bandwidth of LNA due to an oscillator. An electromagnetic (EM) approach is proposed to predict the behaviour of substrate noise at LNA's input. The behaviour of substrate coupling is also evaluated(More)
The design of an UWB pulse generator is presented in the context of low cost applications. The pulse generator is fully integrated in a 0.13 μm CMOS technology and achieves 1Vpp magnitude pulses with only 2.25pJ of energy consumed by pulse and 1.2V voltage supply. The generation method used in this design is well suited for packaged IC using wire(More)
The design of a traveling wave amplifier (TWA) in a 0.13 mum standard CMOS technology is presented. It is designed to maximize the gain-bandwidth product (GBP). Asymmetric cascode, coplanar wave guide (CPW) and losses compensation technique allow to maximize the TWA GBP. Design and modeling of 90 Omega CPW used to synthesize inductors TWA's lines is(More)
