  • Variable gain amplifier circuit
    Patent number: 8779854
    Abstract: A variable gain amplifier circuit (300) comprising a first transistor (310) and a second transistor (312); and an additional transistor (320). The first transistor (310) and second transistor (312) are arranged as common base transistors. The additional transistor (320) is configured to provide part of a translinear loop with the first (310) and second transistors (310). A current through the conduction channel of the first transistor (310) is configured to contribute to an output of the variable gain amplifier circuit current. The circuit (300) is configured such that a current through the conduction channel of the second transistor (312) is copied to the additional transistor (322).
