Bluetooth is a communications standard targeting shortrange wireless communications with data rates of 1Mb/s at 10m distance. To encourage Canadian universities to pursue this commercially promising standard the Canadian Microelectronics Corporation is providing the intellectual property for a Bluetooth SOC Reference Platform. This platform does not currently include an RF transceiver core. Thi...

The presence of resonance frequency offsets often causes artifacts in images acquired with true fast imaging with steady-state precession (true-FISP). One source of resonance offsets is a suboptimal setting of the synthesizer frequency. The goal of this work was to demonstrate that shifting the synthesizer frequency could minimize the off-resonance related image artifacts in true-FISP. A simple...

Frequency dividers are key components for frequency synthesis in wireless and wireline communication systems. Among different types of frequency dividers, LC-based injection-locked frequency dividers (ILFDs) feature highfrequency operation at low power consumption, but their locking range is quite narrow due to the high-Q nature of the resonator. Recently, design techniques to enhance the locki...

While coherently driven Kerr microcavities have rapidly matured as a platform for frequency-comb formation, such microresonators generally possess weak coefficients; consequently, triggering comb generation requires millions of photons to be circulating inside the cavity. This suppresses role quantum fluctuations in dynamics comb. In this paper, we realize minimal version Kerr-mediated microwav...

In this paper, we propose an all-digital frequency output of the synthesizer. High reference frequency (REF) is synthesizer architecture, based on an all-digital XA-frequency used to push the spurs far from the carrier. The need for high discriminator. The new all-digital synthesizer is compared to sampling frequency, in addition to the resolution being previously published work. The architectu...

There are studies indicate that audible sound wave could have effects on propagation growth through catalyzing hearing sense organs, which would bring a series of physiological and biological chemistry reaction. The soundpressure level and frequency are important factors in propagation growth. In this study, an experimental system of audio generator was developed for investigating sound wave ef...

Noise in 4G communication systems is a pressing current problem. There are various ways to reduce phase noise. The sigma-delta passive adder entrenched (PAE) approach was chosen for the WCDMA system because it provides spurious level, noise, and low stabilization time. Therefore, applications, this study proposes frequency synthesizer. It then suggested that addition of before modulator's quant...

Signal synthesis using time-frequency distributions can be improved using an antenna array receiver. The availability of the source signals at di erent array elements allows the implementation of time-frequency synthesis techniques that utilize the source spatial signatures for crossterm reduction and noise mitigation. In this paper, we introduce a new technique for signal synthesis based on ar...
