Patent attributes
Inductor-capacitor oscillators and common mode resonators are provided. The inductor-capacitor oscillator includes a first transistor, a second transistor, an inductor, a first capacitor, a second capacitor, a first winding, and a second winding. The first transistor has a first terminal, a second terminal, and a third terminal. The second transistor has a fourth terminal, a fifth terminal and a sixth terminal. The first, second and third terminals are electrically connected to the fifth, fourth and sixth terminals, respectively. The first capacitor and the inductor are coupled between the first terminal and the fourth terminal. The second capacitor is coupled between the third terminal and a reference voltage. The first winding is coupled between the third terminal and the reference voltage. The second winding is coupled between the third terminal and the reference voltage. The first winding and the second winding are symmetric to each other.
