Abstract
A multi-port active circulator includes a plurality of cascode circuits coupled to one another in a ring. Each respective cascode circuit of the plurality of cascode circuits is coupled to a respective port of a plurality of ports. Each respective cascode circuit includes a common source transistor, a common gate transistor coupled to the common source transistor, and a feedback circuit coupled from the common gate transistor to the common source transistor. Each common source transistor of each respective cascode circuit is coupled to a common junction point.
