Abstract: A power amplifier (600, 700) integrated circuit, which generates an RF output signal by amplifying an RF input signal, includes a thermal-sensing circuit(620, 720), a feedback circuit(630, 730), a logic judging circuit(650, 750), an adjusting circuit(640, 740), and an amplifying circuit(OP1-OPn). The thermal-sensing circuit (620, 720) generates a thermal sensing signal according to the operational temperature, and the feedback circuit (630, 730) generates a power compensation signal according to power variations in the RF output signal. The logic judging circuit (650, 750) outputs a compensation signal according to the thermal sensing signal and the power compensation signal. The adjusting circuit (640, 740) adjusts the level of the RF input signal according to the compensation signal, thereby generating a corresponding 1st stage RF signal. The amplifying circuit(OP1-OPn) can amplify the 1st stage RF signal, thereby generating the corresponding RF output signal.

Abstract: A voltage regulator (30) includes an amplifier (310), a power device (320), a delay signal generator (340), and a voltage-generating circuit (330). The amplifier (310) generates a control signal according to a reference voltage and a feedback voltage. The power device (320) generates the output voltage by regulating the output current according to the switch control signal. The delay signal generator (340) generates a plurality of sequential delay signals each having distinct delay time with respect to an externally applied power-on burst signal. The voltage-generating circuit (330) provides an equivalent resistance for generating the feedback voltage corresponding to the output voltage, and regulates the output voltage by adjusting the equivalent resistance according to the plurality of sequential delay signals.
