Abstract:
1. An amplifier, comprising: a first switch having a first terminal, a second terminal, and a control terminal, wherein the first terminal communicates with a first tank circuit; a second switch having a first terminal, a second terminal, and a control terminal, wherein the first terminal of the second switch communicates with a second tank circuit, and wherein the second terminal of the second switch communicates with the second terminal of the first switch; a third switch having a first terminal, a second terminal, and a control terminal, wherein the first terminal of the third switch communicates with a third tank circuit; a fourth switch having a first terminal, a second terminal, and a control terminal, wherein the first terminal of the fourth switch communicates with a fourth tank circuit, and wherein the second terminal of the fourth switch communicates with the second terminal of the third switch; a first capacitance connected in series to a second capacitance, wherein the first capacitance is connected across the first and second terminals of the first switch, and wherein the second capacitance is connected across the first and second terminals of the second switch; a third capacitance connected in series with a fourth capacitance, wherein the third capacitance is connected across the first and second terminals of the third switch, and wherein the fourth capacitance is connected across the first and second terminals of the fourth switch; a fifth capacitance having a first terminal and a second terminal, wherein the first terminal of the fifth capacitance communicates with the first terminal of the first switch, and wherein the second terminal of the fifth capacitance communicates with the first terminal of the fourth switch; and a sixth capacitance having a first terminal and a second terminal, wherein the first terminal of the sixth capacitance communicates with the first terminal of the second switch, and wherein the second terminal of the sixth capacitance communicates with the first terminal of the third switch.
