Abstract

A circuit includes a frequency doubler circuit including doubler core, an input matching network, and a cancellation network between the input matching network and the doubler core. The input matching network may include an input transformer including a primary inductor, a first secondary inductor including a first terminal coupled to a first gate and a second terminal coupled to a second gate of a first transistor pair of the doubler core, and a first center tap configured to receive a first bias voltage to bias the first and second gates. The input transformer may include a second secondary inductor including a first terminal coupled to the third gate and a second terminal coupled to the fourth gate of a second transistor pair of the doubler core, and a second center tap configured to receive a second bias voltage to bias the third and fourth gates of the second transistor pair.
