摘要： An amplifier, for example for use as an LNA of a radio frequency tuner, comprises a differential amplifying stage (1-5) provided with an AGC core (6-9). The output signals are formed across load resistors (10, 11) at differential outputs (OUT+, OUT-). Compensating stages (15, 16) sum the signals at the differential outputs (OUT+, OUT-) and subtract the resulting sum signal from the output signals so as to cancel the common mode signals including second order distortion products.
