Abstract:
1. An electronic amplifier for receiving a single-ended input signal and generating a differential output signal, comprising: at least two transistors arranged in a differential configuration, wherein the at least two transistors have respective first terminals for receiving signals to be amplified, and a control terminal of a first one of the at least two transistors is coupled through a first capacitance to the first terminal of a second one of the at least two transistors, and a control terminal of the second one of the at least two transistors is coupled through a second capacitance to the first terminal of the first one of the at least two transistors; and a center-tapped differential inductor for converting the single-ended input signal into a differential signal to be amplified, wherein a center tap of the differential inductor is coupled to signal ground, the single-ended input signal is provided to an end tap of the differential inductor, and the differential signal to be amplified is provided at end taps of the differential inductor.
