Sommario/riassunto |
|
In recent years, there has been considerable interest in highly integrated, low power, portable wireless devices. There are three primary areas to be addressed when higher performance and lower power is desired. The first area is the device technology. Scaling of devices has realized steady improvements for many years. The second area is improved circuit design techniques. The final area is at the architectural level. This monograph focuses on the problem of low power GFSK/GMSK modulation and presents an architectural approach for improved performance. The new architecture is a modulated S-D fractional-N frequency synthesizer. The key innovation is an automatic calibration technique, which operates in the background. The availability of the calibration circuit makes high data rate, low power modulation possible. From the Foreword: "The key contribution of the work presented in this monograph is a technique for in service |

automatic calibration of the modulated frequency synthesizer by ensuring that the digital emphasis filter and analog loop filter characteristics are matched. The automatic calibration circuit operates while the transmitter is in service and compensates for process and temperature variation. GFSK and 4-GFSK modulation was demonstrated at data rates of 2.5 Mb/s and 5 Mb/s respectively at an RF output carrier frequency of 1.8 GHz. ... In addition, he presents some valuable tools for the practicing engineer in this field." by Charles G. Sodini. |

Sommario/riassunto |
|
SEEKING THE SMART ONE Twenty-four-year-old Jen Reid had her life in good shape: an okay job, a tiny-cute Seattle apartment, and a great boyfriend almost ready to get serious. In a flash it all came apart. Single, unemployed, and holding an eviction notice, who has time to remember trying out for a reality show? Then the call comes, and Jen sees her chance to start over--by spending her summer on national TV. |

Luckily The Fishbowl is all about puzzles and games, the kind of thing Jen would love even if she wasn't desperate. The cast checks all the boxes: cheerful, quirky Birdie speaks in hashtags; vicious Ariana knows just how to pout for the cameras; and corn-fed "J-dawg" plays the cartoon villain of the house. Then there's Justin, the green-eyed law student who always seems a breath away from kissing her. Is their attraction real, or a trick to get him closer to the $250,000 grand prize? Romance or showmance, suddenly Jen has a lot more to lose than a summer ... |
