摘要： An integrated circuit is described for providing a power supply to a radio frequency (RF) power amplifier (PA). The integrated circuit comprises a low-frequency power supply path comprising a switching regulator and a high-frequency power supply path arranged to regulate an output voltage of a combined power supply at an output port of the integrated circuit for coupling to a load. The combined power supply is provided by the low-frequency power supply path and high-frequency power supply path. The high-frequency power supply path comprises: an amplifier comprising a voltage feedback and arranged to drive a power supply signal on the high-frequency power supply path; and a high-frequency-path supply module arranged to provide a high frequency supply to drive the amplifier, where the high-frequency-path supply module comprises a pulse-width modulator operably coupled to the high frequency supply via a filter and arranged to provide a filtered pulse-width modulated signal to the high frequency supply.

摘要： A feedback loop circuit of a voltage regulator includes a voltage extraction circuit and a loop filter circuit. The voltage extraction circuit receives an error voltage signal that is indicative of difference between an output voltage signal and a reference voltage of the voltage regulator, and generates a voltage extraction signal by extracting one representative voltage for one switching cycle of the voltage regulator according to the error voltage signal. The loop filter circuit applies filtering to the voltage extraction signal to set a feedback signal, and output the feedback signal to a controller circuit of the voltage regulator for regulating the output voltage signal.

摘要： A feedback loop circuit of a voltage regulator includes a loadline and a compensation circuit. The loadline generates a feedback signal according to a sensed current signal that provides information of an inductor current of the voltage regulator, and outputs the feedback signal to a controller circuit of the voltage regulator for regulating an output voltage of the voltage regulator. The compensation circuit generates a compensation signal to compensate for a deviation of the output voltage, wherein the feedback signal generated from the loadline is affected by the compensation signal.
