摘要： In a semiconductor device, a large reduction in the switching noise of the charge pump suppresses jitter caused by the switching noise.
Since the current flowing into the charge pump is equal to the differential current, the residual current occurring in the conventional charge pump is never induced, which enables the suppression of jitter caused by the residual current.
The amount at which the peak current caused by a parasitic capacitance induced when an MOS transistor is switched is sent to the charge pump is reduced, which results in the suppression of the switching noise.
