    摘要: A low noise amplifier includes a first input transistor coupled to an input signal and a second input transistor coupled to the input signal. The low noise amplifier also includes a first output transistor, coupled between the first input transistor and a first carrier aggregation load, configured to connect the first input transistor to the first carrier aggregation load. Additionally, the low noise amplifier includes a second output transistor, coupled between the first input transistor and a second carrier aggregation load, configured to connect the first input transistor to the second carrier aggregation load. Further, the low noise amplifier includes a third output transistor, coupled between the second input transistor and the second carrier aggregation load, configured to connect the second input transistor to the second carrier aggregation load. Also included are a method of operating a low noise amplifier and an extended carrier low noise amplifier.

    摘要: A semiconductor integrated circuit including a differential amplifier circuit, a first output circuit, a second output circuit, a selection circuit, and a feedback circuit. The differential amplifier circuit is configured to operate at a first source voltage. The first output circuit is configured to receive an output of the differential amplifier circuit, output a first output, and operate at the first source voltage. The second output circuit is configured to receive an output of the differential amplifier circuit, output a second output, and operate at a second source voltage lower than the first source voltage. The selection circuit is configured to select one of the first output from the first output circuit and the second output from the second output circuit according to an operating phase determined by an external control signal. The feedback circuit is connected between the differential amplifier circuit and the selection circuit. The feedback circuit is configured to feed the selected output back to the differential amplifier circuit.
