Receiver comprising an amplifier
Abstract:
The invention relates to a receiver (1) comprising an amplifier (31-34) for amplifying an antenna signal, which amplifier (31-34) comprises an amplifier input (11a) and an amplifier output (12a,12b), the amplifier input (11a) being a single ended input for receiving the antenna signal, the amplifier output (12a, 12b) being a differential output, and the amplifier (31-34) comprising circuit (41,42) for reducing a common mode input impedance of the amplifier (31-34).
Abstract(Chinese):
