ABSTRACT:
A high swing cascode biasing circuit includes first through sixth transistors, each including first, second, and control terminals. The second terminals of the first, third and fifth transistors communicate with the first terminals of the second, fourth and sixth transistors. The first terminal of the first transistor communicates with the control terminals of the third and fifth transistors. The first terminal of the third transistor communicates with the control terminals of the fourth and sixth transistors. A resistance communicates between the first terminal of the first transistor and the control terminals of the first and second transistors. A first capacitance communicates between the control terminals of the first and second transistors and the second terminal of the fifth transistor and the first terminal of the sixth transistor. A second capacitance communicates between the second terminal of the fifth transistor and the first terminal of the sixth transistor.
