ADAPTIVE BANDWIDTH CONTROLLED FREQUENCY SYNTHESIZER |
摘要 |
A selective call receiver (100) includes a phase lock loop frequency synthesizer (204) having a programmable output frequency signal that has an associated lock time. The associated lock time is adaptively decreased by using a sink-source-float control circuit (413) that adjusts a loop bandwidth and sink-source-float gain responsive to a frequency/phase error and a prescaled feedback signal.
