    摘要: Switchless carrier aggregation. In some embodiments, a carrier aggregation circuit can include a first filter configured to allow operation in a first frequency band, and a second filter configured to allow operation in a second frequency band. The circuit can further include a first signal path implemented between the first filter and an output node, with the first signal path including a plurality of amplification stages configured to amplify a first signal. The first signal path can be substantially free of switches. The circuit can further include a second signal path implemented between the second filter and the output node, with the second signal path including a plurality of amplification stages configured to amplify a second signal. The second signal path can be substantially free of switches.

    摘要: A carrier aggregation method can include amplifying a first signal with a first current converter to generate a current representative of the amplified first signal, and amplifying a second signal with a second current converter to generate a current representative of the amplified second signal. The method can further include processing the amplified first signal and the amplified second signal with an adder circuit, with the first current converter and the adder circuit forming a first cascode amplifier, and the second current converter and the adder circuit forming a second cascode amplifier. The method can further include providing an output signal at a common output node that is coupled to an output of each of the first and second cascode amplifiers.

    摘要: Circuits and methods related to switchless carrier aggregation in radio-frequency receivers. In some embodiments, a carrier aggregation (CA) circuit can include a first filter configured to allow operation in a first frequency band, and a second filter configured to allow operation in a second frequency band. The CA circuit can further include a first signal path implemented between the first filter and an output node, with the first signal path including a plurality of amplification stages configured to amplify a first radio-frequency (RF) signal. The first signal path can be substantially free of switches. The CA circuit can further include a second signal path implemented between the second filter and the output node, with the second signal path including a plurality of amplification stages configured to amplify a second RF signal. The second signal path can be substantially free of switches.
