Frequency Synthesis for a Low-Power 2.4 GHz Receiver Using a BAW Oscillator and a Relaxation Oscillator
In this paper, a solution to realize local oscillators (LO) for a low power super-heterodyne receiver is presented. The first oscillator uses a bulk acoustic wave (BAW) resonator with high Q-factor. A quasi- harmonic quadrature relaxation oscillator with l ...
2007An Analysis of Flicker Noise Rejection in Low-Power and Low-Voltage CMOS Mixers
The sensitivity of RF CMOS receivers using a direct conversion or a low-IF architecture is strongly affected by flicker noise. This paper gives theoretical guidelines to predict the flicker noise in Gilbert-cell mixers. The conversion gain, the equivalent ...
2001Spectral processing of point-sampled geometry
We present a new framework for processing point-sampled objects using spectral methods. By establishing a concept of local frequencies on geometry, we introduce a versatile spectral representation that provides a rich repository of signal processing algori ...
2001New multichannel Ethernet protocol for passive optical star local area networks using coherent transmission
Philippe Robert, Hector Garcia, Caroline Brisson
A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
