    摘要: The present invention relates to a circuit for providing a signal gain, comprising a first stage comprising a first set of variable gain transconductors arranged for performing phase-shifting of an input signal and providing an intermediate signal, and a second stage comprising a second set of transconductors and a plurality of capacitors receiving the intermediate signal and providing an output signal, wherein the first stage and second stage together form a filter, and wherein the first set of variable gain transconductors and at least one of the transconductors from the second set define the signal gain of the circuit. Further, the first stage may comprise multiple first sets of variable gain transconductors arranged for performing beamforming, each set receiving a different input signal and each having outputs connected in parallel, thereby providing a combined intermediate signal. The present disclosure describes a wireless phased-array receiver comprising the proposed circuit.
