Abstract
A highly linear variable-gain low noise amplifier is constructed using a transistor pair having variable gain control. The gain of the transistor pair is achieved by a segmented resistor having controllable PMOS (or NMOS) components. The circuit includes a variable voltage source and operates to handle wideband radio transmissions via broadcast or cable.
