Abstract

An amplifier circuit formed on a single semiconductor substrate includes a first amplifier having at least one stage for amplifying signals within a first frequency band, a first amplifier having at least one stage for amplifying signals within a second frequency band; and a tapped coil having one end thereof coupled to a stage of the first amplifier and a tap thereof coupled to a stage of the second amplifier. The amplifier circuit may be an RF amplifier circuit, a first portion of the tapped coil serving as an RF choke for said stage of the first amplifier, and a second portion of the tapped coil serving as an RF choke for said stage of the second amplifier. Sharing the tapped coil between multiple band amplifiers increases integration density.
