a number of fractional frequency synthetiseur employing several batteries with recombinant series, process implementation, and radiotelephone using

摘要

The present patent application discusses the use of a frequency synthesizer (903) in a radiotelephone (901). The synthesizer (903) is of a fractional N type. The synthesizer (903) utilizes multiple latched accumulators (1000), within an accumulator network, to perform multiple integrals of an input signal (215). The outputs of the accumulators are combined in series to form a data output signal (229). The data output signal (229) is input to a divider network (111) and used as a variable divisor of the frequency input (119) into the divisor network (111).
