    =====================================

    there will be no dead zone in the cp-PFD conversion function. Several conventional charge pumps turn on both up and down at the same time even when PLL is locked. Due to various reasons such as process, there is a difference of I △ CP between charge and discharge current, even if both switches are turned on, the net current output from the charge pump is not zero, resulting in a fixed value at the instant of each phase comparison, which affects the output of the VCO and results in a Pll lock-out. When the switch in the charge pump is turned off, the feedback of the clock signal and the charge injection into the charge pump switch will affect the control voltage of the VCO, further increasing the phase error and making the VCO control voltage ripple. The overlap capacitance between NMOS and PMOS exists in the mismatch of channel width, which will cause the clock feedthrough of the switch. Since the source and drain voltages of each transistor are approximately equal to the VCO control voltage, charge injection is the main source of charge interference. VC is in the suspended state, the jump phenomenon will make VC voltage discontinuous, become PLL loop noise source, resulting in the output frequency instability. Charge sharing is due to the fact that the up down signal is disconnected when the phase locked, the pull up tube voltage is pulled up to VDD, and the pull down tube is pulled down to Gnd , both of which are different from the output point voltage when both tubes are turned on simultaneously, a disturbance voltage is generated at the output point, which incorrectly raises or lowers the VCO control voltage, resulting in unstable pll operation.
