Mohammad Farazian,Lawrence E. Larson,Prasad S. Gudem's Fast Hopping Frequency Generation in Digital CMOS PDF

By Mohammad Farazian,Lawrence E. Larson,Prasad S. Gudem

Overcoming the agility barriers of traditional frequency synthesizers in multi-band OFDM extremely wideband is a key study target in electronic know-how. This quantity outlines a frequency plan which may generate all of the required frequencies from a unmarried mounted frequency, capable of enforce heart frequencies with out greater than degrees of SSB blending. It acknowledges the necessity for destiny synthesizers to avoid on-chip inductors and function at low voltages to let the elevated integration and potency of networked home equipment. the writer examines intensive the structure of the dividers that generate the required frequencies from a unmarried base frequency and are in a position to constructing a fractional department ratio.

 

Presenting the 1st CMOS inductorless unmarried PLL 14-band frequency synthesizer for MB-OFDMUWB makes this quantity a key addition to the literature, and with the synthesizer able to arbitrary band-hopping in lower than nanoseconds, it operates good in the wanted variety on a 1.2-volt strength provide. The author’s shut research of the operation, balance, and section noise of injection-locked regenerative frequency dividers will supply researchers and technicians with a lot nutrition for developmental thought.
