Abstract: Systems and methods for providing single-ended to differential signal conversion are described. A single-ended voltage signal may be received from an input of a low noise amplifier. The single-ended voltage signal may be coupled to a first input stage to match a source impedance of the single-ended voltage signal to a predetermined output impedance. The single-ended voltage signal with the predetermined output impedance may be output as a first voltage signal to a first converting stage. An input bias voltage may be provided to the first converting stage to bias the first voltage signal. The biased first voltage signal may be output as a first differential-ended current signal to an output of the low noise amplifier.
