Application: High gain low power phase detector and loop filter for phase lock loop (PLL) (Patent ID: US20240213990A1)

The patent filed by Qualcomm Inc. describes an apparatus that includes a phase lock loop (PLL) with a phase detector and loop pass filter (PD/LF) that utilizes a phase/frequency detector, a first capacitor, and a charge pump with a charging path and a discharging path. The charging path generates a charging current to charge the first capacitor based on the output signal, while the discharging path includes a first resistor to discharge the capacitor. The apparatus also involves various switching devices and components to control the charging and discharging processes effectively.

The claims associated with the patent detail the specific components and configurations of the apparatus, including the use of variable resistors, switching devices, and capacitors within the PLL and PD/LF. The method outlined in the patent involves generating a frequency control signal for a voltage controlled oscillator (VCO) by manipulating the charge on capacitors based on phase difference signals. The apparatus and method aim to efficiently control the charging and discharging of capacitors to optimize the performance of the PLL and generate accurate frequency control signals for the VCO.
