Abstract

A device having a reference transistor fabricated within the same semiconductor substrate as a primary transistor (e.g., configured for use in a radiofrequency amplifier or other active circuit) has a shared metallization area coupled to a current terminal of both transistors configured to shield a control terminal of the reference transistor from coupling of alternating current interference from alternating currents within the primary transistor.
