1. A switching system, comprising:
- a first transistor having a first gate and coupled between a first terminal and a second terminal;
a second transistor having a second gate and coupled between the second terminal and a third terminal, wherein the first transistor and the second transistor are configured to conduct a signal current between the first terminal and the third terminal; and
an impedance component coupled to the first gate and the second gate configured to isolate a first gate signal voltage at the first gate or isolate a second gate signal voltage at the second gate to reduce a distortion of the signal current.

Abstract
A switching system includes a first transistor having a first gate and coupled between a first terminal and a second terminal and a second transistor having a second gate and coupled between the second terminal and a third terminal. The first transistor and the second transistor are configured to conduct a signal current between the first terminal and the third terminal. An impedance component coupled to the first gate and the second gate is configured to isolate a first gate signal voltage at the first gate or isolate a second gate signal voltage at the second gate to reduce a distortion of the signal current.

15. A switching device comprising:
-
first and second field effect transistors having substantially matched electrical characteristics, wherein each field effect transistor has a gate, a drain and a source; and
first and second impedance components having substantially same values, wherein the first and second impedance components are coupled to the gates of the first and second field effect transistors and are configured to control a signal current conducted through the first and second field effect transistors by enabling the gate of the first field effect transistor to float to a voltage that is between a drain voltage and a source voltage of the first field effect transistor and by enabling the gate of the second field effect transistor to float to a voltage that is between a drain voltage and a source voltage of the second field effect transistor. - View Dependent Claims (16, 17)
