Claim of US Patent No. 9,112,515

1. A phase-locked loop frequency synthesizer, comprising:
a pulse width modulator configured to receive a reference frequency signal and at least one entry from a frequency table,
and to output N/N+1 modulus signals corresponding to the at least one entry from the frequency table, wherein N is a divider
modulus;

a divide by N/N+1 controllable modulus divider configured to receive the N/N+1 modulus signals and to divide an output frequency
signal by the N/N+1 modulus signals to generate a second reference frequency signal;

a phase frequency detector configured to receive the reference frequency signal and the second reference frequency signal
and to generate an error signal;

a filter network configured to receive the error signal and to output a voltage; and
a voltage controlled oscillator configured to receive the voltage and to generate the output frequency signal.
