  • RECONFIGURABLE AMPLIFIER
    Publication number: 20230283312
    Abstract: An amplifying circuit includes a first reconfigurable amplifier configured to selectively operate in a cascode mode or a non-cascode mode, wherein an input of the first reconfigurable amplifier is coupled to a first input of the amplifying circuit, and an output of the first reconfigurable amplifier is coupled to an output of the amplifying circuit. The amplifying circuit also includes a second reconfigurable amplifier configured to selectively operate in the cascode mode or the non-cascode mode, wherein an input of the second reconfigurable amplifier is coupled to a second input of the amplifying circuit, and an output of the second reconfigurable amplifier is coupled to the output of the amplifying circuit.

  • Reconfigurable amplifier
    Patent number: 11683062
    Abstract: A reconfigurable amplifier includes a first transistor having a gate coupled to an input of the reconfigurable amplifier, and a source coupled to a ground. The reconfigurable amplifier also includes a gate control circuit, and a second transistor having a gate coupled to the gate control circuit, a source coupled to a drain of the first transistor, and a drain coupled to an output of the reconfigurable amplifier, wherein the gate control circuit is configured to output a bias voltage to the gate of the second transistor in a cascode mode, and output a switch voltage to the gate of the second transistor in a non-cascode mode. The reconfigurable amplifier further includes a load coupled to the output of the reconfigurable amplifier.
