Latest Patents

Maoyou Sun holds a patent for a low spur phase-locked loop architecture. This innovative PLL design incorporates a differential Kvco gain linearization circuit with an adjustable DC offset, which effectively reduces clock jitter. The architecture ensures that the free-running oscillation frequency of the voltage-controlled oscillator (VCO) is centered near the desired frequency by utilizing programmable loads. This minimizes the required control voltage range. The PLL's differential architecture includes a charge pump that compensates for variations in Kvco and an LC tank oscillator with a differential controlled varactor. Notably, this design demonstrates the ability to control the reference spur to below -80 dBc.
