Abstract:
A system includes a first circuit, a first charge pump, a second circuit, and a second charge pump. The first circuit has a first power supply terminal coupled to a positive power supply terminal and a second power supply terminal. The first charge pump has an input coupled to positive power supply terminal and an output coupled to the second power supply terminal of the first circuit. The second circuit has a first power supply terminal coupled the second power supply terminal of the first circuit and a second power supply terminal. The second charge pump has an input coupled to the first power supply terminal of the second circuit and an output coupled to the second power supply terminal of the second circuit.
