Abstract
A transmission gate includes first and second transmission path terminals, a series connection of first and second field effect transistors (FETs), and a control circuit. The channels of the first and second FETs are coupled in series between the first transmission path terminal and the second transmission path terminal, such that a channel contact of the first FET is coupled to the second transmission path terminal and a channel contact of the second FET is coupled to the first transmission path terminal. The control circuit is configured to provide a control voltage for a gate contact of the first FET and a control voltage for a gate contact of the second FET, such that the control voltage for the gate contact of the first FET 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 FET is, in the switch-off state of the transmission gate, based on a voltage present at the second transmission path terminal.
