Abstract:
With conventional charge pumps, significant noise is present due at least in part to large changes in the supply current. To combat this problem, a charge pump is provided that includes a number of stages. These stages are coupled to receive periodic alternating voltages having a phase shift with respect to each other so that the changes in the supply current are reduced, which reduces noise.
