| 发明名称 | Voltage modulator | ||
| 摘要 | A voltage modulator (400) comprises a multi-level switched capacitor modulator (44) connected in parallel with a switched voltage regulator (42). An output of the multi-level switched capacitor modulator and an output of the switched voltage regulator are combined, or both connected to an output node, to generate an output voltage. The voltage modulator has an input node to receive at least one input signal and further comprises a control unit (46) arranged to control the switched voltage regulator and the multi-level switched capacitor modulator such that the output voltage follows the input signal. | ||
