Latest Patents

Po-Hao Yu holds a patent for a "Phase-locked loop with novel phase detection mechanism." This invention includes a phase frequency detector (PFD), a controller, a digital-to-analog (D2A) module, and a voltage-controlled oscillator/current-controlled oscillator (VCO/ICO). The PFD features a reference signal input and an input from the output signal of the VCO/ICO, which connects to the controller. The controller is further linked to the D2A module, which converts the control signal from the controller into an analog voltage to manage the frequency and phase of the VCO/ICO. Notably, the PFD employs a novel phase detection mechanism that allows phase detection through signal level transitions of the reference signal input and a delayed reference signal, without requiring edge alignment. This mechanism also provides flexibility in reference signal input.
