Abstract
Methods and systems to control an output frequency relative to a reference frequency. A frequency control system includes a dual-input bias generator to separately receive management and operational controls. The bias generator includes a first bias generator circuit to generate a bias control based on a difference between the management control and a bias feedback reference during a first mode of operation, a second bias generator circuit to generate the bias control based on a difference between the operational control and the bias feedback reference during a second mode of operation, and a bias feedback reference circuit to generate the bias feedback reference based on the bias control. The first mode may include a characterization and/or a start-up mode. The second mode may include an operational mode, such as a feedback-controlled mode.
