Abstract: A method for calibrating a first clock signal output by an oscillation module to obtain a calibrated second clock signal includes obtaining a first count value by counting a third clock signal of an external device. A second count value is obtained by counting a scan signal of the oscillation module, and a first cycle ratio is obtained based on the first count value and the second count value. It is determined whether the first clock signal has a frequency deviation by comparing the first cycle ratio with a reference cycle ratio. A frequency division coefficient of the oscillation module is adjusted when the first clock signal has the frequency deviation, so that the oscillation module divides a frequency of the first clock signal according to the adjusted frequency division coefficient, thereby obtaining the calibrated second clock signal.

Abstract: A gate driving circuit for a charge pump with slowed rates of current change for reduced EMI emissions includes at least one gate driving sub-circuit. Each gate driving sub-circuit includes a first current mirror, a first PMOS transistor, a first NMOS transistor, and a second current mirror. Gates of the first PMOS transistor and the first NMOS transistor receive a clock signal. Drains of the first PMOS transistor and the first NMOS transistor output a driving signal. When the first PMOS transistor is turned on, the first current mirror provides a charging current. When the first NMOS transistor is turned on, the second current mirror provides a discharge current.
