Tunable loop filter in fractional-N frequency synthesizer for wireless applications

A tunable loop filter in fractional-N frequency synthesizer is proposed and analyzed. The proposed concept allows designer to fine tune the loop bandwidth based on current injection into the loop filter. Fine tuning feature can be achieved with the utilization of a voltage-controlled transconductanc...
