摘要:
A multiple output charge pump that includes a first flying capacitor, a second flying capacitor, a first output node, a second output node, and a switching network. The first output node is configured to provide a first voltage, and the second output node is distinct from the first output node and is configured to provide a second voltage, different than the first voltage. The switching network is configured to provide a first mode of operation in which the first and second flying capacitors are connected in one of in series with one another between an input voltage and ground or in parallel with one another between the input voltage and ground, a second mode of operation in which the first and second flying capacitors are connected in parallel with one another between ground and the second output node, and a third mode of operation.
