Abstract

A RF variable gain amplifier with an extended linear tuning range is disclosed. The variable gain amplifier employs a wide swing cascode mirror formed by two cascode transistors and two gain transistors. The two cascode transistors track each other, so are the two gain transistor. The gain transistors operate on the saturation region.
