An amplifier (300) for converting a single-ended input signal (V IN ) to a differential output signal (I OUT+ , I OUT- ). The amplifier (300) comprises a first transistor (301), a second transistor (302), a third transistor (303) and a fourth transistor (304). The first transistor (301), configured in common-source or common-emitter mode, receives the single-ended input signal and generate a first part of the differential output signal. The second transistor (302), also configured in common-source or common-emitter mode, generates a second part of the differential output signal. The third and fourth transistor (303,304) are capacitively cross-coupled. The amplifier (300) further comprises inductive degeneration such that a source or emitter of the first transistor (301) is connected to a first inductor (321) and a source or emitter of the second transistor (302) is connected to a second inductor (322). |
