Abstract
The present disclosure relates to single-ended-to-differential amplifiers and radio frequency receivers. One example single-ended-to-differential amplifier includes a first inverting amplifier, a second inverting amplifier, and a third inverting amplifier. Both an input end of the first inverting amplifier and an input end of the second inverting amplifier are coupled to an input end of the single-ended-to-differential amplifier, an output end of the first inverting amplifier is coupled to an input end of the third inverting amplifier, an output end of the second inverting amplifier is coupled to a first output end of the single-ended-to-differential amplifier, and an output end of the third inverting amplifier is coupled to a second output end of the single-ended-to-differential amplifier. An impedance element is coupled between the input end of the first inverting amplifier and the output end of the first inverting amplifier.
