Abstract
A circuit includes an active balun having an RF signal input and having differential signal outputs, the active balun including a first pair of transistors coupled to the RF signal input, the first pair of transistors including a first transistor of a first type and a second transistor of a second type, wherein the first type and second type are complementary; and an intermodulation distortion (IMD) sink circuit having an operational amplifier (op amp) coupled between a first node and a second node, wherein the first transistor and second transistor are coupled in series between the first node and the second node.
