Patent ID: 8581656

Claim:
A transmission gate for selectively establishing a transmission path, the transmission gate comprising: a first transmission path terminal and a second transmission path terminal; a series connection of a first field effect transistor and a second field effect transistor, wherein a channel of the first field effect transistor and a channel of the second field effect transistor are coupled in series between the first transmission path terminal and the second transmission path terminal, such that a channel contact of the first field effect transistor is coupled to the second transmission path terminal and a channel contact of the second field effect transistor is coupled to the first transmission path terminal; and a control circuit configured to provide a control voltage for a gate contact of the first field effect transistor and a control voltage for a gate contact of the second field effect transistor, such that the control voltage for the gate contact of the first field effect transistor is, in a switch-off state of the transmission gate, based on a voltage present at the first transmission path terminal, and such that the control voltage for the gate contact of the second field effect transistor is, in the switch-off state of the transmission gate, based on a voltage present at the second transmission path terminal, and such that the control voltage for the gate contact of the first field effect transistor and for the gate contact of the second field effect transistor is, in a switch-on state of the transmission gate, based on a voltage present at a ground terminal of the transmission gate, wherein the control circuit is configured to switch the control voltage for the gate contact of the first field effect transistor between the voltage present at the first transmission path terminal and the voltage present at the ground terminal, based on a voltage present at a control terminal of the transmission gate, and to switch the control voltage for the gate contact of the second field effect transistor between the voltage present at the second transmission path terminal and the voltage present at the ground terminal, based on the voltage present at the control terminal of the transmission gate.
