| titleOfInvention |
Equalizer circuit and associated power management circuit |
| abstract |
The present invention provides an equalizer circuit and a related power management circuit. The power management circuit includes a voltage amplifying circuit, which can generate an envelope tracking (ET) voltage according to the differential target voltage, and provide the ET voltage to the power amplifying circuit through a signal path to amplify the radio frequency signal. An equalizer circuit is used in the power management circuit to equalize the differential target voltage before generating the ET voltage. Specifically, the equalizer circuit is provided with a transfer function (including a second-order complex zero term and a real zero term) to cancel the transfer function of the inherent tracking inductance of the signal path and the inherent impedance of the voltage amplifier circuit. Especially when modulating RF signals over a wide modulation bandwidth, utilizing a second-order transfer function that includes a real zero term reduces ET voltage distortion. |
