  • Multiple output low noise amplifier circuit, chip, and electronic device
    Patent number: 11742805
    Abstract: The present disclosure provides a multiple output low noise amplifier circuit, chip and electronic device. The multiple output low noise amplifier circuit includes: a first processing module for amplifying an input voltage signal and converting it into at least two first current signals; a second processing module for impedance matching at the input terminal of the low noise amplifier circuit, and for amplifying the input voltage signal and converting it into at least two second current signals; a voltage output module, connected to the first processing module and the second processing module, for combining the first current signals and the second current signals and converting them into output voltage signals. The low noise amplifier circuit can convert a single input voltage signal to at least two output voltage signals, and is applicable in RF front ends with multiple output terminals.

  • Multiple inputs multiple ouputs RF front-end amplifier circuit, chip and method for configuring signal path
    Patent number: 11742806
    Abstract: The present disclosure provides a Multiple Inputs Multiple Outputs RF front-end amplifier circuit, chip, and electronic device and a method for configuring signal path. The RF front-end amplifier circuit includes: at least two low-noise amplifying modules, each of which amplifies one voltage signal and converts into one or more intermediate current signals; a voltage output module, connected to each of the low-noise amplifying modules, for combining the intermediate current signal output by the low-noise amplifying module and converting them into one or more output voltage signals. The RF front-end amplifier circuit can be applied to an RF front-end with a Multiple Inputs Multiple Outputs structure.
