Abstract
A direct digital synthesizer (DDS) such as a Quantized Interpolated Edge Timed (QuIET) synthesizer is implemented in the feedback path of a translational Phase Lock Loop (PLL). The frequency translation introduced by the synthesizer reduces the amplification of reference feedback path noise sources, thereby enabling a wider loop bandwidth and improving high-pass filtering of phase noise without the addition of a second PLL.
