Abstract
Low-noise amplifier having programmable-phase gain stage. In some embodiments, a radio-frequency amplifier can include an input node, an output node, and a programmable-phase gain stage implemented between the input node and the output node. The programmable-phase gain stage can be configured to operate in one of a plurality of gain settings, and to provide a desired phase for a signal at each of the plurality of gain settings.
Claims15
A radio-frequency amplifier, comprising:
- a common input node;
- a common output node;
- and
- a low-noise amplifier implemented in a cascode configuration between the common input node and the common output node, and including an input stage and a cascode stage, the input stage configured to operate in one of a plurality of gain settings, and to provide a compensating phase shift for a signal at each of the plurality of gain settings, the compensating phase shift selected to provide an approximately constant phase among the plurality of gain settings.
A semiconductor die having a radio-frequency circuit, comprising:
- a substrate;
- and
- a low-noise amplifier implemented in a cascode configuration on the substrate between a common input node and a common output node, the low-noise amplifier including an input stage and a cascode stage, the input stage configured to operate in one of a plurality of gain settings, and to provide a compensating phase shift for a signal at each of the plurality of gain settings, the compensating phase shift selected to provide an approximately constant phase among the plurality of gain settings.
A radio-frequency module comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a low-noise amplifier implemented in a cascode configuration on the packaging substrate between a common input node and a common output node, the low-noise amplifier including an input stage and a cascode stage, the input stage configured to operate in one of a plurality of gain settings, and to provide a compensating phase shift for a signal at each of the plurality of gain settings, the compensating phase shift selected to provide an approximately constant phase among the plurality of gain settings.
