Abstract
A system and method for modulating a phase component of an electromagnetic signal includes a phase/frequency detector having first and second inputs and an output. The first phase/frequency detector input may be configured to receive a reference signal. The system may include an oscillator having an input and an output. The oscillator may be configured to generate a desired oscillator output signal at its output. A divider may be configured to receive the oscillator output signal. The divider may have a divider count input and a divider carryout output that may be connected to the second phase/frequency detector input. A loop filter may be connected in series between the phase/frequency detector output and the oscillator input. The loop filter has a transfer function including at least two frequency response rate change points, where each of the frequency rate change points corresponds to a pole or a zero in the transfer function.
