Abstract

A frequency selective circuit includes a first transistor, an impedance element, a first capacitive element, a second capacitive element, a second capacitive and a second transistor. The first transistor includes a first terminal, a second terminal and a control terminal. The impedance element is coupled between the first terminal and the control terminal of the first transistor. The first capacitive element is coupled to the first terminal of the first transistor. The second capacitive element is coupled to the control terminal of the first transistor. The second transistor includes a first terminal, a second terminal and a control terminal, wherein the control terminal of the second transistor is coupled to the control terminal of the first transistor.
