Abstract
Embodiments provide a configurable low noise amplifier circuit including a gain stage coupled to the input of the low noise amplifier circuit, the low noise amplifier circuit being configurable between one of a first topology in which the low noise amplifier circuit includes a degeneration inductance whereby the low noise amplifier circuit operates as an inductively degenerated low noise amplifier, and a second topology in which the low noise amplifier circuit includes an impedance matching stage coupled to an input of the configurable low noise amplifier circuit, the output of the impedance matching stage providing an input bias voltage for the impedance matching stage, and a feedback stage coupled to an output of the impedance matching stage and a voltage source, the feedback stage providing a compensated operating voltage for the impedance matching stage.
