Embodiment Construction

[0025] The prior art receiver illustrated in FIG. 1 comprises a prior art antenna stage 2 and a prior art amplification stage 3 . The prior art antenna stage 2 comprises an antenna 4 which is grounded through one side of a balun 5 . The other side of the balun 5 is connected to the antenna stage output via capacitors 6 and 7 . The antenna stage outputs 9a, 9b comprise differential outputs. Ports 9a and 9b are biased by having a voltage V CM The connected center-tapped inductors 8 are connected to each other. Capacitors 6 and 7 and inductor 8 together form a prior art impedance matching network.

[0026] The prior art amplification stage 3 comprises a prior art low noise amplifier 10 comprising amplifier inputs 11a, 11b and amplifier outputs 12a, 12b. Amplifier inputs 11a, 11b comprise differential inputs comprising ports 11a and 11b, and amplifier outputs 12a, 12b comprise differential outputs comprising ports 12a and 12b.

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 a device (54) for compensating a series input impedance of the amplifier (31-34).

Description

technical field [0001] The invention relates to a receiver comprising an amplifier, an amplifier and a method. [0002] Examples of such receivers are wireless receivers, wireless transceivers and wireless interfaces. Background technique [0003] A prior art receiver is known from US 2003 / 0042983 A1 which discloses a receiver comprising an amplifier for amplifying a radio frequency signal (antenna signal). The amplifier includes two transistors, an amplifier input, and an amplifier output. The emitters of these two transistors form the input of the amplifier, and the collectors of these two transistors form the output of the amplifier. The input to this amplifier is a differential input, and the output of this amplifier is a differential output. [0004] In order to interface a single-ended antenna with a differential input, a balun must be used. When located on-chip, such baluns require a relatively large chip area and result in signal loss and increased noise figure. ...
