Patent abstract
A wideband low power active isolator that may operate with a low voltage supply and provide improved linearity and insertion loss is described. The active isolator includes parallel connected common gate amplifier and common drain amplifier that are implemented using active transistors. A RF choke configured to suppress RF signal is coupled between input to the common gate amplifier and the ground such that the common gate amplifier also functions as a current source biasing the common drain amplifier.
