Multi-modulus counter in modulated frequency synthesis

摘要

An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate an output signal in response to a reference input and a feedback signal. The second circuit may be configured to generate the feedback signal according to a plurality of moduli in response to the output signal, a first control signal and a second control signal. The frequency of the output signal may be modulated in response to the second control signal.
