Latest Patents

Shaoyong Lu holds a patent for a "Phase locked loop with sub-harmonic locking prevention functionality." This invention relates to type-I PLLs that do not lock at a sub-harmonic frequency of a reference clock signal. The technology involves controlling the timing of charging or discharging of capacitors within the PLLs. The phase frequency detector (PFD) in this PLL design prevents sub-harmonic locking by generating a clear output signal. This signal ensures that the sampling capacitor of the PLL's loop filter discharges only when it is not being charged. By implementing this mechanism, the PLL's voltage-controlled oscillator can maintain its intended frequency, avoiding oscillation at a sub-harmonic frequency.
