Abstract
Provided are a low-phase-shift variable-gain amplifier and a method for processing a radio frequency signal. The low-phase-shift variable-gain amplifier comprises: a differential cascode amplification circuit, which comprises a common-source transistor and a common-gate transistor, wherein a gate stage of the common-source transistor is connected to a first bias voltage via a target resistor, and a gate stage of the common-gate transistor is connected to a second bias voltage; a current-steering structure, wherein one end of the current-steering structure is connected between the common-source transistor and the common-gate transistor, a third current signal outputted by the current-steering structure is used to adjust a gain of the differential cascode amplification circuit; and a phase compensation circuit, wherein one end of the phase compensation circuit is connected between the common-source transistor and the common-gate transistor.
