Phase frequency detector and charge pump
Phase-frequency detector (PFD) is used to form a control signal VCO tuning. PFD compares phases of divided VCO signals and divided reference oscillator signals and detects phase difference. Charge pump generates pulses for the loop filter. This structure includes ECL charge pump and CMOS charge pump.
The block is fabricated on iHP SiGe BiCMOS 0.25 um (SGB25V) technology.
