GEOGRAPHIC LOCATING REMOTE ENDPOINT MONITOR DEVICE, SYSTEM, AND METHODOLOGY THEREOF |
摘要 |
A phase-locked loop frequency synthesizer includes an L-state pulse width modulator configured to receive a reference frequency signal and at least one entry from a frequency table, and to output at least one N/N+1 modulus signals corresponding to the at least one entry from the frequency table. The synthesizer includes a divide by N/N+1 controllable modulus divider configured to receive the at least one N/N+1 modulus signals and to divide the output frequency signal by the at least one N/N+1 modulus signals to generate a second reference frequency signal. The synthesizer includes a phase frequency detector configured to receive the reference frequency signal and the second reference frequency signal and to generate an error signal. The synthesizer also includes 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.
