Abstract: A variable gain amplifier is disclosed having parallel sets of transistors and control for bias voltages, wherein the average of bias voltage values is strategically controlled to reduce phase variance. For example, a variable gain amplifier may include a first set of transistors coupled to a first bias voltage, a second set of transistors coupled to a second bias voltage, where the second set of transistors is coupled in parallel with the first set of transistors, and a control module adapted to control the first and second bias voltages, the control module adapted to reduce the gain of the first set of transistors while increasing the gain of the second set of transistors.
